It's amazing that Sega fans really can't let go it's like seeing kids wishing for santa at xmas. Sega is never coming back into the hardware realm the best you can hope for is another mini console or unrelated plug n play. Even getting them to release a saturn or DC mini would be a push, people always going on about the diehard fans but in the realworld they mean shit it's easy to talk about the glory days but sega needs people to buy stuff not just talk about it. MD mini was only created because it was cheap to do so, to even try to do their later consoles it would end up been so expensive they would take a hit as outside the bubble of fandom they will not sell enough to make it viable.
They are no longer in a position where they can throw away millions on hardware risks, they fucked up in the md era with pointless hardware additions and slowly paid the price which is why we only get games from them now.
