Incorrect. They may not be a Sony studio but Sony would have been the ones that referred Comcept to Abstraction. Why do you think they also worked on the PS3/Vita ports of Hotline Miami and Knytt Underground? It's not a coincidence.
I just think you're wrong that this had nothing to do with Sony. Given everything we know I'd bet that Sony were the ones that pointed them towards Abstraction in the first place.
