It does seem kind of like a dead month but I'm sure there will be plenty of surprises coming our way at E3. Maybe it's to make room for a virtual console release?
Major releases sure but there are indies each and every week so far. Should pick up after E3 of course. Nintendo has 2nd largest place only behind Sony so that should tell you something. Nintendo has traditionally missed E3 in favor of Directs so clearly they have major announcements coming our way
