I wish you good luck sitting confortable on your sofa and using the wiimote + nunchuk + keyboard :)

On PCs you use the same controller (keyboard) for both playing the game and communication. Using one controller for playing and another for communication is ...

 That's a pretty good reason for nintendo never to make one.

Yes you're probably not the norm but these days I don't think any of the top raiding guild would ever consider recruiting anyone refusing to use vent, I know my guild would not and I know the top worldwide guilds make it a defacto requirement for anyone applying.

Trying to do Sunwell without vent and without any mod is just asking for failing miserably...(between dodging a billion aes and fighting not to waste a GCD people really don't have a lot of time to read chat these days, that is of course not the case for the more casual players although those tends to use mods too, just not the same than the raiders).

The thing is mods allow the user community to make up for the short-comings or the lack of some features in a game. It's a given that any MMO trying to compete with WoW would not be able to spend at the start the same amount of money that Blizzard is spending on Wow which means they will have to provide the player base some ways to do some of the stuff themselves in the meantime...

PS : the best selling game this year isn't going to be GTA4 or WiiFit. It's going to be the next Wow expansion, and by a wide margin at that ( provided chinese release is simultaneous to NA one this time).

 I started raiding with the guild long before Vent became prolific within the world so we seemed like dinosaurs near the end. That said, we also had 2-3 deaf/partially deaf healers which meant we all had to resort to typing anyways. I, of course, used the various boss mods just to make an encounter workable.

 Don't get me wrong, just hearing it tends to be a thousand times easier for 99% of the population. Our healer crew suffered dramatically from trying due to people like me who start to tune out various sounds when I focus, and the best of our healers not being able to hear at all. I can't comment on the top-end of WoW these days, of course, since I long ago retired. I can say I have heard the same arguement a thousand times and everytime my guild proved it was workable. Most under-estimate how easy it is to recognize a line of chat and know exactly what it is. The learning curve becomes steeper naturally, but once you learn to recognize the basic shape of the sentence you spend literally a tenth of a second glancing at it before knowing precisely what it says. I can go over this in a lot greater detail if you atually care to debate the pros and cons in PMs rather than clutter this thread more.

 The mod issue for WoW is a huge one though, I concede. You can make an MMO, and have it be successful, without the ridiculous modding community however. A lot of the reason mods are so required for various funtions is because they are so present. An encounter starts to be designed around the idea that a mod is there to do functions x, y, and z. Remove that element and UI mods become much more optional than mandatory.

@FaithRaven:

Wiimote + keyboard. Why would you want to use the nunchuck at all? Wiimote as a halfway decent mouse replacement and leave everything the same. 

You just said it, "wiimote is a halfway decent mouse" so why not use a real mouse instead?

Keyboard is a no-no for using it on consoles games. Most people play their consoles from their sofas beds etc with no surface in their front where to hold the keyboard.

They day I'll see keyboards used for console games will be followed by the day when mouse is also used and its quite clear that in the 3rd day that console won't exist anymore.

 Because the Wii lacks mouse support. This is a topic about Nintendo possibly being the best hope for a console MMO. I don't think it would work so well over-all honestly, but there is a chance Nintendo could pull off a succesful MMO.
