Friendly heads up: you can now nab a preorder for MM25: Mega Man and Mega Man X Official Complete Works from Barnes & Noble for $44.99. B&N currently has the release date set at August 28th. Pending official word from UDON, however, we can't be sure if this is an absolute or tentative date.
I'll work on getting some form of confirmation. In the meantime feel free to preorder. I'm certain Amazon will follow suit shortly.
UPDATE: A good friend from UDON confirms the date to be accurate. We'll have more news very soon!
