I guess I can try and start a games-centered discussion.
Candidates for launch window software from Japanese 3rd parties, presumably to be announced by September?
-From Capcom, I think some sort of fighting game port will happen. Lots of candidates. I also have a feeling Dragon's Dogma is a port candidate. Game is finished so presumably there would be time, and I suspect Capcom is desperate to see more sales for the franchise. Part of me thinks Capcom and Nintendo has some sort of Monster Hunter 4 version in the pipeline, but it also would not surprise me if the series is strictly portable from now on. Maybe Basara as well as it was a Wii franchise.
-From Namco Bandai, I wonder if we'll see some sort of Tales port, given that Shocking Alberto said Nintendo is eager to see another mainline entry on Wii U. Ridge Racer, One Piece, also possibilities.
-TecmoKoei seems rather chummy with Nintendo, so something like Samurai Warriors and/or other musou games seems like a good bet. I would also bet on Dead or Alive coming sometime during the launch window.
-SE? Who knows. The biggest question is probably when will DQX arrive and what type of impact will it have. I also wonder if SE would try and port over FF13/13-2 to get some easy sales from Wii owners who missed out.
-I also would not be surprised to see Level 5 with some decent support for the system- maybe Inazuma or a Ni No Kuni port.
-Konami. Literally expecting nothing.
Sega- they did not really give the Wii much Japanese-centered support so not expecting much there.
-Atlus? Who knows.
Basically, I expect a decent amount of ports of 2012/2013 stuff, which would still be 100% better than the launch window lineup for Wii. Samurai Warriors, Tales, Inazuma, and possibly Monster Hunter seem like the best bests- franchises which had a Wii presence.
