I haven't heard much about Mega Man 9 besides what James Rolfe (the Angry Video Game Nerd) has said, but I'm a classic Mega Man fan, so I'm definitely interested in that.
Besides those two titles, I'm rather intrigued by the selection of virtual console titles. If you haven't figured it out already, I'm a classic gamer so it's really hard to pass up.
With all that said, I don't have the money to buy a Wii right now. I could be wrong, but I have a feeling it may not be long before the launch of a new line of next-gen consoles. I'm also rather interested in a PS3 and an Xbox 360 so it's a little hard to gauge what I should do right now.
