Straight from Kaz Hirai's TGS 2007 keynote is the news that two development studios have been taken under Sony's first-party wing.
First off, BigBig studios has been acquired. They're known for such titles as their Pursuit Force series.
The second development studio that Sony has acquired are the Motor-riffic folks behind one of PlayStation 3's most popular titles, MotorStorm. With more than a million copies sold thus far, it'll be really exciting to see what Evolution Studios has up their sleeve for the coming year.
More news from TGS 2007 on the way shortly.
