You really need to decided what you want out of it.
Wii, solid nintendo, games, good family games, wireless internet built in, games and additional remotes cost about the same, biggest downside IMHO is lack of HD output, on my 50 inch plasma, not so impressive…. Manageable.
Xbox/PS2 better gaming platforms, way more powerful, better graphics full HD, lesser made for kids, with Kinetic about $100 more than a wii. IMHO more bang for the buck.
Both a good systems and ways to go, but xbox/ps2 will play all thr new games and play them well, games like call of duty are pretty weak on the wii, games like Mario party and wii party IMHO make up for the dazzling graphics with really good game play and no real need for super graphics.
IMHO go play with them in the stores and don’t worry about a wii 2, at this point.
