Nintendo finished its E3 keynote a little while ago and after being bored half to death by some of the less interesting announcements, Nintendo announced not only Super Mario Galaxy 2 but also a new Metroid game called Metroid: Other M.
This game is not another Metroid Prime game and it’s not being developed by Retro Studios. Instead, this looks like a side scrolling Metroid game much like the original Metroid and the popular Super Metroid.
Super Mario Galaxy 2 was also announced, starring not only Mario but finally brings back his dinosaur steed Yoshi. If you haven’t seen the trailers for these games I recommend you look them up on the Internet. You won’t regret it.
