Anything is possible. Your comparison to NT is still not that strong.
Insomniac has seen their continued success with Sony, something NT had with no one.
Money isn't the only factor in play here.
Tarsier is someone Sony used to help with projects rather than mainline them, so maybe not that lucrative a move from Sony's POV.
Housemarquee seems to be working with Sony on a new game. But their games are low sellers. Still it would be a great buy if HM can move up to higher budget titles.
From is never happening. The already belong to a very successful multi media company.
I am just saying what the expert saying, also i am already wrote this back on my previous thread http://gamrconnect.vgchartz.com/thread.php?id=240190&page=1
I'm not denying that Sony will buy more studios if it is possible.
I do think that there are candidates that ppl want which aren't as likely as they seem. From Software is an example of this.
I also don't think Sony are just going to buy studios for smaller scale games; that is something they can easily partner up for instead.
