Yea, so planning on getting one of these for Christmas (don't plan to get both of them now, or probably ever).
Wii would be cool for a couple of weeks but as said, couldn't see myself playing it much on my own.
360 has the better catalogue atm? Also cheaper (but not so sure price is a big issue seeing as I'd probably own the console for 6 or so years anyway). A big plus for me is Live (supposedly superior to the PS3 alternative, although they're creating a new service soon? - what's that about) and the fact that most of the people I know have 360s rather than PS3s (would obviously prefer to play people I know rather than internet randoms).
Meanwhile PS3 has some games I'd probably like to buy in future (FF stands out) and is more powerful. I normally play RPGs and Sports - not a big FPS fan but I'd play it if it was good (but at the same time wouldn't go out and buy 3 different FPS games)
What to choose?
