Back in April, it was discovered that Capcom filed a trademark for the title 'Mega Man Universe' at the U.S Trademark and Patent Offices. Now the name has reared its head once more, this time at the European trademark offices -- a sure fire sign that the game, whatever it may be, will be releasing in Europe too.
Other than trademarks, no other details about Mega Man Universe exist at this point, merely fan speculations. With E3 '10 going on all this week, perhaps we'll finally hear something. Till then, keep on speculating.
UPDATE (6/15): Okay, now this is interesting. The Mega Man Universe trademark has just been spotted over at the Japanese trademark offices -- Mega Man Universe, not Rockman Universe. Hm...
