I understand the sentiment, but from what I can see the important ingredients that made the Dreamcast great have mostly been lost. To me, the Dreamcast was the swansong of arcade gaming culture, a culture that has largely disappeared. Sure, there were some games without that type of focus (I'm still hoping I'll kick Lan Di's arse one day), but I fail to see what the mere existence of Dreamcast 2 would do to encourage publishers to move away from making what works for them in the short term.
