As a simple point of fact, I am correct.  Ultimately it is all relative.

Why would one game's release date shift automatically alter the timing of others?  As long as Sony secures a range of content by purchasing studios with generally specific focuses.  GT5 is the biggest game Sony has, period.  They need a certain feature-set and a certain level of quality and would wait for it.  Whilst I disagree with the level of pressure you imply Sony puts on devs, their applying ANY pressure makes my point entirely correct.

You directly corrolated the situation under Sony as being identical to "Rainbird's" 'free' situation as an independent.

If by "a" freedom you mean 'some' freedom and also 'less freedom' by definition than any independent developer, then I agree with you.  If you truly believe what you clearly stated, that there is no differences (or even no substantial differences) between the freedom of independent developers and the freedom of Sony first parties then that, clearly, is naive.

Sony is ultimately a business (sometimes quite a ruthless one) and firms are purchased as part of a business plan.  The diversity you speak of is across the entire stable of Sony titles, with each acquired dev required, at least to some extent, to fit the game plan.

Buying Quantic Dream makes actually more sense for Sony then buying any other 3rd party company avaliable.

Sony owns the IP to their Exclusive games anyway. If Sony decides to make a new Heavenly sword now, they don't neccesarily need Ninja Theory for example.

but Quantic dreams is different. they are the guys who made "Heavy Rain" but they don't go on making Heavy Rain 2 and 3 they make a different game, a new IP, but they will known for Heavy Rain.

And if they get hired by another company and make a new game, they are still the "guys who made Heavy Rain"

Their name is worth more then the name of the IP in my opinion.

If this is true, it isn't a mystery why they would go with Sony. As bad of a rep as Sony has they do treat their companies well and provide quality control. This will also help them increase budgets for their titles. Heavy Rain 2 anyone? Microsoft needs to learn something from this, true or not.

Finally someone gets my point!

To be honest, I don't give a crap about who QD develops games for, all I care about is that they get the tools to create the best possible games they can. They could make games for the DS for all I care, so long as they feel that it's the most suited platform for their games, and that's what I want to preserve.

more ps3 exclusives the better. i cant wait to see cages next title

Then they WILL create something new and exciting for Sony's platform next generation.

But they would do it because they had to. Basically, QD should have the creative freedom to choose whatever platform they want to develop for, as I believe that next generation will see very different consoles, where the big three try to differentiate themselves through interface rather than power. As QD have shown that they like to work with new interfaces and ways of interacting with a game, locking them down to Sony's platforms for all eternity is a bad idea in my opinion.

There's been a big discussion about it in the thread already if you want more details...

Quantic could make a Heavy Rain 2 this gen. Sony isn't dropping the PS3 for a PS4 anytime soon.

I think next gen Sony is going to do what they are doing for the NGP, listening to their developers for what they want in the HW.  Plus, I doubt next gen will be much different from this gen.  All 3 will have their own motion controls from the start.  This probably means an improved PS Eye that may be able to pull off what the Kinect does, only better.  Not sure if they will go for new Moves or just have the same ones from this gen work for it.  Either way, I'm sure Sony will have them covered on whatever type of game they will want to make.  At least, not any less than MS or Nintendo would have them covered.
