New IPs for the new Console are the best bet to have massive success
Just look at Ubisoft top 10 selling games list. It is all new IPs. Nothing from their past comes close to the new IPs they made in this current generation of games.
Grand Theft Auto sold like crazy on PS2... but not as much on X360/PS3 even though cost more to produce
I can give many more examples... but basically new/fresh will beat old/stagnant everytime they make equal quality product with equal level marketing support.
