Pulling the 8GB to 4GB would not upset the developers so much as they have already been working only with 4GB. I myself thing the 8GB is not even necessary. Don't even think there the developers will be able to use much more than 4GB (they usually don't in PC games even when pushing it to the max).
Reducing it to 4GB would actually be a good move for sony. Only fanboys could actually think otherwise.
are you speaking of the same developers that sony thenselves said they increased the RAM to 8 gigs for?( who were after the conference declaring their satisfaction with the RAM ) or other developers we've never heard of?
one thing i must say though is that your concern for sony is touching lol
