If they made a Mega Man game that is to Mega Man X, what Mega Man X is to Mega Man 1, they could potentially recover some of what they have lost.
If it just and just had a really decent cast of characters/bosses/level design/music/plot that wasn't completely ridiculous and rebooted the series they could do well. Even if Megan Man 11 were to arrive and be better than 9 I'd be happy. I loved 9, I thought 10 was a step backwards. Not unlike how I hated mm6 compared to the first 5. Or X4+ after X1-3.
But for some reason they have let their core franchise grow wild and die on the vine.
A new Strider game would be an easy PSN title to put together.
RE6 looks ambitious, if not very fun or interesting. They could easily reboot the Dino Crisis idea, or tweak it into a new IP though. Much like the characters in it, RE just won't die.
Dragon's Dogma was good enough, even great at times. Sadly it was also terrible at times, and its DLC is adding nothing to the game so far.
I'd like to think that they only have room for improvement with DD2, but it could easily turn out to be the next Dragon Age 2.
I've never cared for DMC, and I sold Bayonetta the day after I bought it. Action may be good, but you can only tolerate so much bad plot and characters between ass kicking. Not even the fan service could cover a game that made me feel soiled to play it. Especially when the fanservice crosses past the line from alluring to cartoonish and pre-juvenilely insipid.
I'll just appreciate the fanmade hentai, and you can keep your fucked up game thank you.
They could also surprise everyone with another new IP that excites people.
