So... wow. From the looks of it, we just bared witness to some sort of robot uprising taking place within a dystopian classic series universe -- yet -- the trailer cuts to footage of Iris, Alia and Signas (X series characters), toiling away as if they're providing aid to the very situation at hand. Classic/X series crossover, anyone?
According to Stoo.com, the source of the trailer, the game will indeed feature characters from both series, specifically outlining the presence of classic Rockman, Blues (Proto Man), Forte (Bass), X and Zero. Just how these characters will relate to one another is unknown at this time so it's up for speculation.
Aside from the above tidbit about characters, no new details about the game were reveal. However, once again, various Korean sites are promising more details will trickle out in the near future.
If you're new to this whole Rockman Online hubbub, allow me to summarize what we know so far: Rockman Online is a side-scrolling action RPG, boasting 3D graphics on a two dimensional plane, much like Mega Man X8 and Maverick Hunter X. Familiar faces and NPCs will make up the game's cast in addition to online players.
The game is being cooperatively developed by Capcom and NeoWiz with plans to distribute the title exclusively in Korea and Asian markets by the end of 2010. While there's been no word of a release for the West, a Japanese release is likely, if a trademark is to be believed.
