upcoming release schedule, with the guide now penned for release on April 11th, 2012.
Before you start celebrating, it should be noted that this is a projected release date, albeit the most accurate according to the UDON crew. Nothing is absolute just yet, so it might do well to keep your fingers crossed, too. I've reached out to UDON for further confirmation, but I've yet to hear anything back; I will update with new information as it becomes available.
The Robot Master Field Guide will serve as a handy compendium of the classic series universe -- chock full of character profiles of every major Mega Man character, hero and villain. It's a very special book that's being carefully prepared; for fans, by fans. Hopefully, it will be in our hands soon enough.
