What this looks like is they just want to package up the existing items into one box. No changes in the retail products, just a new coat of paint for the discs and a box.
Information on PlayStation 3 DLC will be available soon.
The ps3 version of ME2 shipped with several DLC items on the disc: Shadow broker / Overlord / lost memory / Cereberus code so I'll bet the reason they aren't mentioning that is because they are just going to stay quiet about the extra content on the PS3 ME2 disc so that PC / 360 fans don't get upset that they are not getting those in this package.
Or they could be planning to create a new version of the ps3 ME2 game and remove the DLC.
I picked up a copy of ME3 for $10 on PS3 at best buy recently and I can get a new copy of ME2 for approx $15. If I buy that PSN version of ME1 for PS3 at $15 that comes to a whopping $40. Without the DLC rounding out this package $60 is just expecting consumers to pay you an extra $20 for a box. And does anyone like these fold out boxes? I'm much happier with either a case that hold multiple discs or multiple cases. These fancy paper fold out things are annoying as hell.
