Uhm, "none of the above"...?! -Seriously, I don't care, since I don't even remotely have any money to spare on a new console... -but IF that was the case, I'd go for the PS3 (I already got the PSX & PS2, and sony's controller-setup + game-adaption suits me fine...)
No offence, but IMO anything Xbox-related suxx... mostly cuz of their f*dup controller's button-setup!
When I saw WiiMusic at E3, the first thing that popped in my head was "This is the short bus version of Rock Band." Then I was disappointed to see Mega Man 9 would be a retro 8-bit, they could have atleast gone with the sprites from the MM8. But this strip [link] explains that.
I tend to change the consoles a lot. I take if a good game would be released on the PS3, I would play that one and love it... right now I'm more playing on the 360 and the DS... But I love the Genesis (truly) and the PS1 (because of the best games I ever played). And... darn, the PS2's quite good too... Wouldn't want to live without KH anymore even though it's so widely known that it can even get painful to talk to fans (a friend got jumped on in the bus because he mentioned KH. By a total Stranger. Quote? EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!! KINGDOMHEARTS!!!!!
Honestly I could care less. All three consoles are too expensive and it would cost less to only do upgrades, that way we can keep the consoles and avoid taking up space and we don't have to lose several games we love to play and play new games also.
