recent famitsu interview, it's floating around somewhere. might even be in the OP of this thread.
it says that kickstarter is the primary funding source. doesn't take a huge leap of logic to see that means sony and other additional funding sources aren't putting anything over $2 million into the project.
See, the problem with your statement is that you don't know what Yu's expectation was.
Do companies like Harebrained and Inxile expect their Kickstarters to only hit their goal and nothing more? No, obviously not.
Probably the most we can extrapolate from his statement without a huge leap in logic is that it won't be a large amount like $5-10 million
