Yup. The fan service thing is something people have been saying for a while.
I've always found it to be that odd 'Sony loves us all' mentality you see at E3 every year.
Sony wanted this to be a commercial success.
If they didn't they wouldn't be releasing it this time of year first of all; and they wouldn't be making at all.
Their a business.
I mean I don't think Sony fully understand their audience, who they are or have the ability to cut between 'FANS'/'fans' and 'customers'; so maybe it was 'fan service' but it is designed to be profitable 'fan service'.
Of course Sony wants the game, every game, to be a commercial success. The fan service commentary it's my own, it does not represent Sony expectations to this game, I think. I think this game has little appeal to anyone outside the Sony most knowledgable fandom, and Sony misjudged its appeal if it trusted on a new IP in a very difficult genre, and unproven to Sony, to support PS3 sales in this holiday season.
