well I play WoW, Tabula Rasa, various FPS's, and used to play Guild Wars using an XBOX 360 controller hooked up to my PC. I haven't set it back up since I wiped, though I've been meaning to. There are more than enough buttons for most cases, the toughest being anything non-melee in WoW since most people are used to loading gobs of spells onto their action bars.
For people talking about how it would dumb down Guild Wars...well hello, I haven't come across many people yet that haven't joked about how dumbed down Guild Wars is (oh, you just select the enemy then press space to go to them lol.. oh your character just follows and keeps facing the enemy? lol oh you just press C then space for the next enemy once he's done? lol). Now I love Guild Wars and prefer it over most of the others I switch out on, but the interface is almost as dumbed down as you can get in an mmo. Anything more and you've got Diablo (which is pretty slick for what it is - an action rpg).
NOTE: I wasn't laughing because I know Guild Wars is supposed to be more about skill (or was).
The fact that you only use 8 skills max in the first place reinforces that.. Try switchblade out sometime for those of you interested in paying with an xbox 360 controller you have. It works with quite a few games more than the blades support - great in Tabula Rasa). Guild Wars is a bit awkward because of the C space, but it still works out.. Melee in woW is great and it lets you kite really easy (assuming you are able to play with a controller).
On one of the new consoles, everyone would have access to voice chat (got vent? got ts?), whether they could use it or not, it's there. I agree with a previous poster that due to the relationship of NCSoft and Sony nothing they make will end up on the 360 most likely. I have both plus PCs, and even though I prefer the 360 over the ps3, the ps3 is still quite a capable machine. Even more, every PS3 has a hard drive.
People have had some good arguments about keeping wow off the console because they aren't required to discipline themselves to only 8 skills (or from the other side, it's not dumbed down to using only 8 skills like some kind of action rpg), but there's not much of a reason at all for some kind of GW to work on a console. Too many people have it blocked out in their mind. Some of you may not remember the days when games started using the mouse and many people stuck with keyboard gaming, thinking that was stupid.
The graphics would be fine. Even for someone like me that plays on a 30 monitor at 2560x1600 it would be fine because I don't notice a difference between that and 1920x1200. As a side note I set it to that so it doesn't have to change from my desktop resolution since nvidia keeps RED ENGINE GORED ENGINE GORED ENGINE GORED ENGINE GOing up its vista drivers.
Both consoles have a (functional, though crappy) keyboard accessory, though with voice chat and the difficulty of getting used to the mini keyboards, I'd welcome less BS in the chat channels without having to turn them off. There is also the mouse/keyboard option for the PS3, but if you are going to use that, I'd rather be at a desk instead of on the couch (where I play my consoles). Keyboards/mice just seem to unwieldy to me on the couch (even had a remote one and I don't care for the gyros).
The thing is, someone someday will think outside the box and pull it off. That's all it really takes is thinking outside the box and thrwing out pre-conceived notions. The reason, I suspect, that it hasn't been done yet (except Phantasy Star Online and FF) is because as we all know none of the big players are really into taking big risks. Doing anything for the first time is a big risk, and ANet was probably up for it when it was first founded, but they won't be taking any more risks I suspect - with the titles that came out and the fact that GW2 sounds like WoW 1.5.

If any of you are going to QuakeCon, you'll find me there once again with my 360 controller gaming away (well, unless I'm playing an RTS or downloading pr0n, but Civ Revolution - from someone that thinks outside the box, namely Sid Meier - may change that as well)..
as a final note, its unfortunate that the deal is with Sony as they seem to RED ENGINE GORED ENGINE GORED ENGINE GORED ENGINE GO up MMOs on the PC, much less trying one of a console.
