There isn't going to be a Sega console,Sems. Not now and not for the next decade.
Nope sorry, got to defend Semmie here.
The one message that you have to take away from this is that you can't say for certain what will happen.
I agree that a console is unlikely, but a couple years ago I would have smugly laughed at a Genesis branded laptop or a Sega Toilet arcade. 10 years is a long time and anything can happen.
Maybe Sega no longer has the muscle to put out a top tier console, but maybe another hardware manufacturer comes to them with a partnership agreement, or maybe the market opens up to a second tier console (like the WiiU) and Sega decides to put something out.
There are quite a few avenues for Sega to gamble. Hell if Android takes over Sega could release a Sega phone or tablet (wait they already did with Tokio Technology) and continue to march along with their digital strategy.
To bring up the laptops again, it really shows that Sega and the world hasn't forgotten that it used to make consoles.
Again highly unlikely, but definitively can't say that there won't be one in 10 years.
