Retro Studios will most likely have a new IP to show at E3 2010.
When you look at the titles that EAD have developed this generation, they mostly make sense. I think the only two games that Nintendo could have scrapped/changed completely were the holiday titles of 2008, Wii Music and Animal Crossing: City Folk. Apart from those the EAD titles have all made perfect sense.
Look at the expertise the respective teams have:
