No, it would completely ruin their company. They're making some money off of developing for other consoles, but I can't imagine they have enough money to run against Nintendo, Sony, and Microsoft in a console war. However I was a Nintendo kid, I had a Genesis but never found anything great on it aside from Jurassic Park: Rampage Edition, and Chakan: The Forever Man. They really liked colon's. I also had a Dreamcast, and again I never played any games on it that amazed me. I think it's better if they just keep making third party games and not throw their entire company behind a losing battle in a new console war, unless they start putting out mind-blowingly awesome games to bulk up their wallets beforehand.
