Hi Cobbler, yeah from what I can gather, they've added an additional burner to the 2000 series like the 3000 series, something I reckoned they should've done from the start as I've always considered the 2000 series to be like a Holden Commodore with a 2 litre motor, yeah it'll get the job done but is under powered to be really useful. It has almost twice the real estate as the Baby Q but only 4 BTU more so this new 2800 should be just what the doctor ordered.
I only just recently bought a brand new Q3200 with Natural Gas before all Natural Gas appliances stop selling. The only disadvantage of NG is that if you move house, you need to go to a place with NG connected. It's great to get it so damned hot that you've wound the needle off the temp scale and not worrying about emptying the gas bottle.
I can see the 2800 being a big seller actually for a semi portable grill, when I had my Q220 many years ago, it cooked shish kebabs for over 50 people at a friend's birthday party so having that extra grunt could be a good thing. They've gone basically 17 years or more without much in the way of improvements or design as it's been when you're on a good thing stick to it but others like the Ziggy have caught up and overtaken them in the power stakes, and admittedly, I almost went with the Ziggy triple burner before I settled on a Q3200 only because I wasn't confident with Ziggy's lid down grilling capabilities even though they say you can grill high heat with lid up but that's not the way I prefer....you just get used to the Weber Way of doing things.
