Mass Effect Trilogy Edition Game Save [Regions Related on PS3]

 First of all, this is my first post here, but had an EA account since 2009 and used it here. But ever since Mass Effect 2 was announced on PS3, i started visiting this site in the hopes of BioWare/EA rereleasing the trilogy on PS3, and what do you know that is business and they did it.
So, Hello everyone!

 I have played Mass Effect 3 which is a region 2 game on a region 2 PS3 (PAL). I have sold both Mas Effects on PS3 so that i can buy the Trilogy Edition. I do want to know if i bought the game from Amazon.com (US) will my multiplayer carry over or not? Or if i bought the game from amazon UK will it carry over or not?

Because i know that DLCs in the UK dont work on games from other region 2 countries. I do want to know if this applies to game saves too, and if by any chance the multiplayer save works cross-region.

Note: I have directly asked the Producer on the PS3 version of the game and he said that it should carry over to a region 1 game from amazon.com. Full tweets here.

Note 2: I did once buy Mass Effect 3 Region 3 by accident and it imported the Region 2 Mass Effect 2 game save normally.
