It's ok to focus on new IP. Treasure generally steered clear of sequels (and when they did them they were usually really different). Sega for a long time put most of its weight behind new IP, especially when moving to new systems.
But for that to work you need ideas and shit. People want to see Rare do throwbacks because no one really cares about anything they've done in the last decade (at least).
