Before anyone gets their hopes up. With exclusive additional content it is widely assumed that they are purchased by Microsoft. However we have never had real confirmation of this. For many of the more colorful members of the community this is the only justification for a developer to not also port the content to the PS3. That isn't necessarily the case mind you.
In any event Microsoft may pay for some timed exclusivity. However they never openly talk about it. Except with this particular content. Which they paid out fifty million dollars in advance for. The fact that they played that up in the press is a pretty good indicator that it is bought outright. Not to mention I find it hard to imagine Microsoft spending that much on a timed exclusive so that Sony could get it without paying.
From most stories and rumors we read. Microsoft refuses to pay for anything that is even in the remotest sense connected to PS3 game development. Which is basically what they did with this cash advance. They paid for the development in not so many words.
The answer is no. No need for wild assumptions or convoluted logic to get that.
