Forum:ME3 Collector's Edition

Bioware has mentioned before that they are working on an "Uber" collector's edition for Mass Effect 3. Anybody have any idea what this might entail? Otherwise, what would you like to see in a possible Uber-Edition?

Personally, I'd like to see one or more of the following (leaving out art book, because that's pretty much a given): -Model M8 assault rifle. Hey, Gears 2 did it with the lancer. -Model Normandy. Why this doesn't exist already is beyond me. YOU CAN GET ONE IN GAME, WHY NOT IN REAL LIFE!? -Extra content/characters/missions not avaliable in other editions

I'd like to hear other people's opinions or if anyone has any actual details yet.
