EDIT: Actually Buzz is new in N.A. There does appear to be a 2007 Movie Edition, a 2005 Music, & a 2006 Sports version only in Europe. But we have not had any Buzz titles in N.A. until October 2007.
Before the Wii I was (am) really the only hardcore gamer at my home, though my kids did play a few casual games like Mario Party & Mario Kart on occasion, and FX-Zero as well as a few PS2 racing games, but not much more than that. When we had company over we normally played board games, but now our friends who would have never have played video games will come over asking to play (I'm mostly speaking of the wives in this case). Most of our friends do not yet have Wii's, but almost all of them want them. And not just friends with kids. They don't have them only because they can't find them, and they won't wait in line at 5 am to get one.
BTW, my kids are now playing Zelda, We Love Katamari, SMG, GT4, Guitar Heros, Kindom Hearts, Mercury Meltdown Revolution, etc. So they are still basically pretty casual, but they have MUCH more interest in games now, they even know when SSSB & Wii Fit are being released, and have been talking about 360 games as of late too (Scene-It, Rock Band, Viva Pinata).
And they all want a DS, we are going from a 1 to a 3 DS family by Christmas. And I think I'm going to be forced to buy Singstar as well :(
Anyway, I think all the systems will benefit from N's expanding the market, and all will increase sales in '08. Including Wii.
Do you think handhelds will continue to increase as well?
