Unfortunately for you both we're dealing with EA here, Bioware themselves might have done something generous like give us new endings for free, unfortunately EA isn't going to let that happen... I bought CE of ME3 and have already spent an additional $40 on Multiplayer alone in a misguided attempt to unlock all characters needless to say it failed, I'm only missing the Turian Soldier
For ME2 I purchased literally every piece of DLC, money well spent... I don't mind paying for DLC if it's for a good game.
Also Paradox, I'd contact EA about that... I had the same thing, only my From Ashes unlocked... I had to plead my case to get my soundtrack and armour both.
Also not to crap on your parade Obrusnine, but they only said they were going to provide content that would give clarity to the endings, not that they would make all new ones...alot of people misinterpreted that for what they wanted to hear, (including countless gaming news websites) I was one of those people at first, but the admin on the Mass Effect 2 (the legit page, funded by Bioware) page on facebook corrected that for me... basically the endings will be the same, they're just going to try to make them acceptable, scumbag Bioware is scumbag. I personally think the game could have benefited from another few months to a year in the Development oven... as somebody who uses RPG Maker VX to make my games, and does a better job than they did at that, you can tell EA cripple Bioware with time restraints, I refuse to believe this is what Bioware intended.
EDIT: Clarification ONLY DLC confirmed as fact yet again.
Though I did see one interesting theory (no not indoc.) That the Stargazer telling the story at the end was a representation of Bioware and the child represented the players so the last line of "one more story about the shepard" is hinting at another sequel, despite us being led to believe this was the finale... I also refuse to believe EA OR Bioware would drop a product that successful in just 3 games... their shit endings gathered support that led to over $80,000 in donations, that alone shows that Mass Effect 3 is by far singlehandedly the most controversial game of all time, that attention is probably what Bioware wanted, we can on speculate :/.
