I've said this before, but even though I think weber should build a kamado, I seriously don't see that happening.
Look at Weber's line up. They are dependable, long lasting, durable and not the least bit innovative. If you look at Weber's charcoal grills, they are for the most part repackaging the same concept over and over. Except for the GA, their idea of "branching out" is "make it smaller...now make it bigger...ok now put it in a table...now a different table...What?!?! You want me to make it bigger AND put it in a table? No WAY! that's way too much!!!"
I can't see them jumping on the steel kamado bandwagon any time soon.
