Well, with Sega stating not that long ago that they want to win back the fans and release quality games again, I can see them going back to their history of games and porting them to the PS4, X1 and/or Wii U.
Shenmue Collection IS coming, as the moment the Shenmue 3 Kickstarter launched, I thought "Welp, guess the HD Collection will be coming next year to help hype up Shenume 3
". That isn't an unrealistic expectation to have and with the Kickstarter being so successful, Sega has the 'interest' in the series to warent for sorting out the liscencing issues to get the games on PS4/X1/Wii U.
JSRF is possible too, as is Skies of Arcadia, as both should be easy ports to make and even if they don't do super well, it will be a sign of good will to the fans in allowing them to experience the games again on new hardware
.
I jumped at the chance to get the 'Dreamcast Collection' (SA2, Jet Set Radio, Nights) the moment they came out because I want to play Sega's history of games, as I never owned a Dreamcast or Saturn (did play SA2 in the past on my GC though). I would buy JSRF, Shenmue Collection and Skies of Arcadia the moment they come out
.
So, I hope this does happen
