Built-in touchscreen – One of the biggest things to look out for in the latest version of Wii could be the reported touch-screen controllers in the console. The new controllers could feature a six-inch high resolution screen for gameplay
Faster three-core IBM processor – The new Wii is also reported to be powered by a new three-core processor from IBM that makes it much faster than arch-rivals Xbox 360 and PlayStation 3
Backwards compatibility – All the older titles for the Wii could be supported in the new version
Faster Graphics – The new system could also be powered by a dedicated Graphics processing unit from chip-maker AMD's ATI R700 family
Increased RAM – The new Wii could also boast of 512 MB of dedicated RAM
A new name – It would obviously have a new name. It is code-named Project Café inside Nintendo, but it could be named Wii HD when it actually hits shelves
Debut Date – While it will be announced at E3 tomorrow, the actual console may not hit shelves till fall 2012
