I doubt it. Would they really have made that deal with Nintendo if they were going to create their own console? Also, I can't read Japanese but I think that text says "Entertainment something", probably Entertainment System or something similar.
Dreamcast One; charges for all game activstions as if they were new, online "always" not true; can play single player offline...once you activate the game online!! Oh, that was another system. Yeah, false rumor on Sega system.
I remember there was a buzz like this with the "Dreamcast 2" back in 12.12.2012. SEGA doesn't have the financial backing nor does it have any interest in manufacturing mainstream home consoles under its current management - they're busy making video games and arcade machines, the latter of which aren't making a huge buzz anyways.
Pretty sure Sega can't afford to make a console. They'd actually be bankrupt.
Not to mention the Sega we all knew and loved, they're dead. They're gone. They're never coming back. The Sega we have now is part of Sega Sammy, which is mainly dealt with Slot machines in casino's I think, could be remembering it wrong.
But yeah, Sega... I should say Sega Sammy doesn't have the funds to make a new console, develop games, advertise, package it, ship it and everything.
