I wonder if the scores (platinum, bronze) are equivalent to the Famitsu scores the games received. All I know is that 428 got a 40/40 for some reason, and looking at the other titles, I imagine the ratings match up. But I'm too lazy to look this information up to confirm it. The anime titles sound about right - bronze - if the scores correlate.
Supposedly they've picked 75 (!) games for this already. No telling if they are third party only at this point. I'm sure plenty of us would like to see some first party titles, especially given the ones Nintendo has already announced as being out of print. They should also push games like No More Heroes. I've noticed most of these titles would be considered more "gamer" in nature versus casual, which may or may not be the case when more are announced.
I'm not expecting a North America announcement before A) E3, and B) before a European one. Seems like the boys across the pond have the drop on us lately, and E3 would be the best time to announce this sort of thing. Which means it wouldn't happen before fall. This is all my speculation.
