Where did you hear that? I want to know if it's safe to get excited for that Megaman X collection...
Game Informer issue 126, "The Good, Bad & Ugly" section. The two volume Mega Man Collection is mentioned in the "Loose Talk" section.
The two titles they were most hyped over were the MM Chess (Jap) and the little-known MM Soccer (Released in US but more or less overlooked by all but the hardcore MM/RM fans).
Unfortunately, GI is the only place where this second collection is mentioned. I'm not saying that it can't be true- in fact, I hope to the powers that be that it is true. But CoA hasn't officially announced it, just the first one.
Its possible. I don't think CoA would leave X out. Now... if only they would include the 5 GB games too.
