Hell, I'm all for new IP's, but the fact stays that sucky developers make sucky games, no matter whether new IP or sequel. I should have saw it coming that Dead Space was a cheap RE/SS ripoff. I'll never ever buy a new game from an unknown studio.
As for rights hands: That means that the devs don't mess around with already perfect gameplay mechanism. I wouldn't trust a nobody developer to make a System Shock sequel.
