At the start of this generation I was planning on getting a Wii to start with and PS3 later after it came down in price after a year or two.
It did come down in price, but I am more satisfied with the wii than I expected. So, for right now, I am thinking I spend too much money and time on games and probably will not be getting a PS3 or 360 anytime soon. I would rather pick up another 8 or more games for the wii than pick up a PS3 with one game.
I might eventually still get a PS3 eventually... but probably not until I can get it for $200 on ebay bundled with a dozen games.
I am a little disappointed that more quality games are not coming to the wii, but... honestly there is more than enough that are that I don't care.
