I haven't read any of the above so apologies if it's just repeating ;P
1. Worldwide release (give or take a week maybe) in May
2. hopefully between £150 and £200 or even cheaper!
3. revolution, nun-chuck add-on, controller, hopefully some form of freebie like a demo disc or even a game - not counting bundles :P Mario 128 bundle
4. oooo erm..... £20?
5. 1 Controller and chosen add-on - maybe £5 dearer if you buy a controller with an add-on rather than just a controller
6. Black, White, Red, Purple, Blue (in order of likelihoodnessism <-- I know)
7. Toss up between black or white... probably white as I have a sexy black cube *sings ebony and ivory*
8. Mario 128 (or whatever it's now called)
