Sup guys, just bumping this with some updates of possible anime for winter 2010/2011. All of this is right off FansubWiki, so pretty reliable.
Description off MAL: Tsutsui Yukitaka was a freshman who had just entered a high school, and he was hoped to be a good baseball player. When he moved to a new apartment, there was a man in the room. He said he was an alien and lost his memory.
Actually, he was the first prince of Planet Dogra, and he was the man who had the best brain and the worst nature.
Description: EVERYONE HAS TO HAVE HEARD OF THIS! Some original magical girl SHAFT anime with widefaec loli with bows and guns.
Description off Wiki: Suite PreCure♪ (スイート プリキュア♪ Suiito PuriKyua♪?), also called Suite Pretty Cure is a Japanese anime series and the eighth series of the Pretty Cure anime franchise by Izumi Todo. Produced by Toei Animation, the series will premiere on February 6, 2011, replacing HeartCatch PreCure! on its initial timeslot. From the title logo, the series theme will be related to music.
Houkago no Pleiades
Description: some collaboration anime between Subaru (yes the car company) and Gainax. No description as of this post other than a trailer of a night sky and a girl staring at it.
In addition to my original list, looking forward to Madoka Magica, Level E, and possibly Houkago no Pleiades once more info comes out.
