When will more wii third party games be announced?

[Veder Juda]

I don't think there are a lot of game announcement during the run up to Christmas, except in Japan where Christmas isn't very important; game companies would rather focus on games they're selling over the next few months, rather than hype up games not due out until next year, or even later.

TGS is at the end of September, so there will probably be some announcements then.
