Train wreck on 04 December 2013
Sony going third party would mean that Sony would continue the general theme that has plagued Nintendo in that they will just ignore them (like the majority of 3rd parties).
Sony would probably shift some games over to the 3DS but would focus (like many third parties are starting to do) on mobile. They would use the proceeds they get from the sale of 3DS games and use it to create a new mobile studio to focus more on their mobile business.
