okay, while you made some decent points to begin with, you quickly devolved into just console war flame bait troll territory, imo.
Do you know for sure the PS3 version really delayed DLC? The amount of DLC to support ME2 is way beyond that of ME1, which only had... one expansion? Also; iirc the next dlc is supposed to be something that serves to pave the way to the events of ME3, and is the only forthcoming expansion.

and your final point, which you admittedly said is the last on list of issues, is the one I take biggest issue with.
Welcome to the current generation.
Your collectors edition isn't so special anymore? People are buying the DLC that you got a timed exclusive on with your extra edition? Be glad you didn't have to wait, or pay extra for it (beyond the collectors premium price).
With Fallout 3 I paid for each of the DLC expansions, $10 at a time. Then the GOTY edition comes out, with all the DLC on the disc.
Same with Borderlands.
Dragon Age: Origins Ultimate edition?
Countless games have had console specific dlc or preorder bonuses that later have become available to all gamers at an extra cost.
If its going to bug you, you might as well wait a year to buy a game for when the goty / ultimate edition comes out with all the dlc at no extra price.
