Fumbles,
I have had multiple conversations with Motorola about this new structure and how it seems to "confuse" many games that save their data folders to the "real" SD Card, so they do know about the affects now (although they admit not thinking about large game data folders), and I'm still not sure what will be done but I SURELY WOULD NOT try to change/rename things because I think it could really mess things up.
BayouFlyFisher may be right about it being the future of ICS, but all I know is it could be a headache if apps and games stop working and started saving data all over the place (in the wrong places). That's just my opinion.
