No, the parent company is 100% relevant. It's basic economics and accounting. Explaining that, to you, if you don't get it already, would take more time than I care to spend on the topic.
I've heard quiet rumblings that PS4 may never happen b/c of the failings of Sony as a whole. 50% in a year? That's just plain awful. Also, margins in the console/entertainment industry are rather miniscule, volume is the key, and microsoft/nintendo are still owning sony in that regard.
Edit: Since you felt like tossing on that last... ridiculous... paragraph, I'll take this chance to explain how you're wrong yet again. Then I'm going to go watch Cabin in The Woods with my wife, I hear it's pretty funny.
SCEA is a part of the umbrella organization that is Sony Corp. The head of SCEA, whatever his name is, reports to Sony Corp, not vice versa. Sony Corp. owns all rights, intellectual property, physical land, equipment, buildings, etc. If Sony is failing, you are failing. Picture Sony Corp. as a human, the brain being Sony Corp. itself, if that brain fails, you... the leg, die. You're not parallel, you're not "target india vs. whatever you were trying to talk about", you are a subsidiary of a larger company, if they fail, you do.
Now have a good evening fella, I'm sure you'll be Bill Gates come this time next year.
