Street fighter is the biggest fighting franchise ever and it is the kind of game people usually play on arcade > console > PC. Arcades are not a big thing now, so PS4 will get a huge boost.Some people can argue that Xone has KI which makes SF "pointless" to them but KI never was a big fighting game.The remake didn't set the world on fire too so i expect street fighter 5 to give a huge boost for PS4.
-Tomb raider is beloved classic franchise,but is a shadow of it former self.Plus most part of the fan base is on playstation/pc for historical reasons.If the PC version exist it will canibalize pontential hardware boost plus playstation fans have uncharted 4 at the same time frame which makes tomb raider 2 "redundant" to them.
So imo SF 5 will have a bigger boost.
