Online gaming support
It seems to me that this is being released. Yes, it should've been available at launch with many currently released titles having online gaming. However, it seems silly to scream about Nintendo needing online when they already plan for games (being released this year) to include it.

Original content on the VC
It'd be cool. But, it's definitely not a make or break the system issue. I think it'd be awesome if Nintendo updated some of the older games and added an achievements type system to it. It'd be cool for say, Super Mario Bros to have achievements for beating the game without warping, beating the game under X time, beating the game without dying. It'd allow the life of the VC games to live off of a little more than the Nostalgia factor.

The use of Mii in more games
Yeah, right now there's not much point to them. It'd be nice if some games started taking advantage of them as well as them being your online avatar. If Nintendo has a firends list, it could "skin" your Mii to the game you're currently playing online. Like, if you're playing Metroid online, it'd put your Mii in a Samus suit (of your favorite color) and if someone selected your Mii it'd jump them to the server where you're playing (provided there's room).

Frequency of big titles and original franchises
Definately. I don't know if Nintendo itself can release big title more frequently, but it'd be nice if Nintendo put a little more focus in original IP. My biggest compliant is the 3rd party developers porting a game and slapping on some piss poor controls. Hopefully, this will occur less often in the future since developers will (again hopefully) be spending more time on the development of Wii titles.

Intuitive gameplay experiences
This, IMO, is where Wii developers need to put their focus. They need to focus a lot more on the controls when they're developing games. What's the point of using the remote to race when I tip it on it's side and the only way it's different from playing a game on the NES is a little bit of tilting? How about my nunchuck works as a steering wheel and the remote is used to shift?

But how many of those people who are hooked on Wii Sports will also buy Wii Need For Speed?

Also, I hate to say this, but it would honestly be too hard to create a control scheme for the Sixaxis or 360 controller. There's just too many functions and things to do.dgsag
