When a Publisher bails out/ comes to the rescue of a game (how ever you want to word it) like Sony did with Heavenly Sword, they have the upper hand in contract negotiations and the developer usually in return for financing/ debt alleviation basically becomes the same as an out of house developer that's given a fixed contract to make a game that some one else's property .
On one hand you may get completion and some short term employee tenure and keep from going under always a good thing plus if everything goes well future contracts , the down side is you have to give up most of the profits and maybe the IP itself and go from a studio that gets finance for its property's to becoming a out of house contractor, it also leaves you having to find funding for your next project with out being able to use the profits generated by a successful game.
All up the thing that seems to rear it's ugly head is ambition outweighs financial sense and in Brendans case history, delivery in a reasonable time frame and on budget.
