As noted already, Sony is the only one really hyping future games right now. The 360's line-up appears largely known, but more may be coming before the holiday season.
Wii, really we have no idea. Nintendo has stated they won't be hyping up games until they are soon to be released (so only 2-4 months in advance). Also we know a lot of 3rd parties have opened Wii studios or redirected resources. We don't know what any of those studios are doing currently, and AAA games probably won't be announced until the Spring or Summer of '08.
So like '07 where the Wii started with a mostly bare cupboard but is ending with a bang, '08 will likely play out in a similar manner.
So in a nutshell, we really won't know until we get there.
