Sucker Punch makes the great
inFamous series and Sly Cooper games and they've been doing Sony some good the past years. So good that Sony's gone up and
bought them outright.
Sucker Punch is now solely owned by Sony, which is their 16th studio that they own. Formed by former Microsoft employees, they've been making Sony exclusive content for many years now so it makes sense for Sony to snatch them up. It also helps they make some very high quality games.
Being they were independent, some other company could have easily come in and bought them with the right price. Sony was smart enough to keep them in the family so future Sucker Punch games will definitely only appear on the Sony platform, even though that's all they've been developing for.
Let's hope this acquisition doesn't affect their work.
