I have confirmation from a source that for 2022, Weber is introducing redesigned Genesis gas grills. The name "Genesis II" is being discontinued, as is the old model scheme of E-315, E-335, S-435, etc. in lieu of simply "Genesis 3-Burner" and "Genesis 4-Burner" grills.
Work surfaces are said to be larger but have a slimmer profile. The propane tank has been moved back inside the enclosed cart. The cooking surface consists of a split grate system with a standard cooking grate on one side and a souped-up modular GBS-type system on the other side with a variety of interchangeable cooking surfaces. These grills continue to have a dedicated Sear Station burner and some include Smart Grill technology already featured in some Genesis II and Spirit grills.
Some models include integrated lighting of the grill surface.
No information on colors, pricing, or timing of availability yet.
What's striking to me is that another model year has passed without a revision to Summit gas grills. Maybe something mid-year coming up?
