Is there any sign of a killer app that will be the push I need to buy a Wii?
Existing games sound okay but nothing unmissible (or maybe someone would say Paper Mario or Zelda are particularly special).
As far as forthcoming games: Galaxies is said to be cool (but a descendent of Geometry Wars from another platform ), Manhunt 2 has so much attention that they've made it illegal here in the UK
Perhaps MPH3 will be something special, but I got bored of FPS about 9 years ago.
Maybe the killer app for me would involve the Wii interacting with the DS (like the PS3 DVR/PVR does with the PSP), as was suggested for future games.
If I don't get won over and buy a Wii soon, I'll buy a hi-def TV and then will think a 360 or PS3 would be the only way to go. It would probably be a PS3 since I can't stomach the idea of having to pay for online membership.
