June 1st can't come soon enough.
I just perorder the ps3 verison So is sega handling the ps3 version or is obsidian Alvin?
I'm not a developer, but I guess answering to you would be quicker than letting you wait their answer (nice guys developers, but also pretty busy) : all the three versions of the game have been developed in-house at the same time, which is what you were asking I guess, so no port done by some SEGA's company or anything like that.
Thanks for answers my question Can't wait for two more weeks ...got it paid in full $64.64..my poor wallet:(
