@Idahawk We've been closely inspecting them for about a week or so now and just had product training on the new models yesterday. Overall I feel its a better grill than the previous generation and they have definitely taken steps to improve on some weak points that needed to be addressed. That being said there are a few changes that some people will like and others will not...
Key positive points:1) Burners! These are the real deal. REALLY nice flame pattern and they are a heavier gauge stainless than previous tube style burners. LX models also have the ability to run a "High+" heat setting that gives 20% more heat across the entire grill. This replaces the somewhat gimmicky "sear station" with a much more practical system. Here's a pic I snagged from google but this is exactly what it looks like in person:
.
Another nice bonus is that you no longer need any tools to change a burner out. They simply pop out of the holding slot and the new ignitor can snap straight off rather than having to slide it sideways like previous models.
2) The electrode itself is significantly improved and is now completely sealed to better protect against water infiltration. The ceramic casing feels much more durable and is now smoothly polished compared to the more porous feeling of the older model. The ignition module has also been redesigned with a couple smart improvements - 1) it is now also fully sealed, and 2) the battery compartment is angled downwards so that if moisture does creep inside it will drain away from the important connection points. This was a common issue on older models so its nice to see an effort to fix that. Finally, all electrode wiring is now Silicon coated for better performance against weather and heat.
3) Warming rack. Although it takes a try or two to figure out the operation I really like the fold away warming rack. It's also "elevations" compatible so many existing accessories will work with it easily.
4) Frame Stability/Maneuverability : I'm surprised a few people have mentioned that the cart feels flimsy. In reality it now has welded lower connection points and seems more solid than before in my opinion. The larger wheels on the one side also make it easier to move around. Rubber treads are nice touch too...
5) Lighted control knobs on LX models. These should have been included in the Genesis line a LONG time ago. Better late than never
6) iGrill 3 Compatibility: In addition to temp probes - on LX models you can see the tank propane level and turn on and off the control knob lights. Kinda cool.
7) Less body seams on the front face: Previous models would collect crud and grime easily in the gaps between components. With the new beveled front lip I think it really cleans up the look and will be easier to clean and maintain.
Potential Concerns:1) The propane bottle shield is a bit awkward for sure. Doesn't make much sense to me that it doesn't cover the entire tank. They should have gone all or nothing here IMO.
2) Fold down tables are a nice feature for many, but the rotisserie mount must be removed to drop the side table down. Not a huge deal if you only use it once in awhile but not overly convenient either. The table once folded down is also still fairly wide so in reality you only are saving 6 or 8" in width. Again, not bad but not great either. You also cannot lift the grill using the side table, they say to collapse the table and use holding points on the frame and/or cookbox.
3) Plastic end caps on tables. Although they seem very sturdy and durable some folks including myself will miss the steel/cast versions.
4) Too many models? I suspect they are eventually going to phase out the Spirit line but who knows... in the meantime there are a LOT of different Weber grill configurations available and therefor customers can get exactly what they want feature-wise. It will be interesting to see which models become the "favorites" of the bunch. We're all stocked up for spring!
Final note:
The best advice I can give is to check them out in-person at the store. After reading all the internet rumors etc I had more or less made up my mind before even seeing the grill in person. But after actually seeing it with my own two eyes and inspecting it for a few days its definitely growing on me more and more each day. I'd be happy to rock one on the back patio if it wasn't already filled with kettles
@LightningBoldtz - You're right, Napoleon makes a VERY nice grill as well. My father recently upgraded his gasser at home and went with a Prestige model and loves it. The side ceramic sear station burner option is just amazing for steaks. Both Napoleon Grills and Broil King are based here in Canada.
@kettlebb - Broil King grills use a very shallow cookbox and run notoriously hot... could also be a regulator issue as you mentioned. Hardcore steak guys love them
