"Other M" was different-enough of a name that people could freely choose to believe it wasn't canon. It wasn't even made by the same company as the previous entries. Metroid Prime 4 is a different matter entirely. If it sucks, it will severely hurt the brand.
Yeah I was about to say that if Metroid survived Other M, it can survive a soylennial entry.
