Yeah, the ending was screwed. Everything else - wonderful.
From what I hear, the original ending went something like this:
Depending on who you have higher INF with, Kreia or Artis becomes Darth Traya. She gathers the sith, or something, and leads the attack on Telos. You defend Telos, and follow her to Malacor V. While in HS, if you're male, either Handmaiden or Visas comes and talks to you about going with you to defeat Traya. You tell her, No, she has to stay and train the Jedi who will follow you, and Revan, into the unknown regions. You land on Malacore V. Everyone else, somehow, manages to get away from the Hawk, and confront's Traya. She, single handedly, defeats all of them. Some may die, some don't. If you chose LS Male, Atton dosn't die. If you chose LS Female, he gets away, but is attacked by Sion, and you find him right before he dies. You then go and confront Traya, and (hopefully) kill her. If you chose LS Male, then on your way back to the Hawk after the battle, you run into Atton. He says something along the lines of "Where you going now? Well, where ever you're going, I'm coming along. I mean, who's going to save you, if I'm not there?" The Hawk launches, and you head off into the unknown regions.
The thing about the Remote/G0-T0 scene is this - HK-47 would show up, and depending on LS/DS, he'd either destroy G0-T0, or G0-T0 would activite programming he hid in HK, and have him destroy Remote.
I'd assume that the Mira/Hanhhar scene would be something like this : The group's going to confront Traya, and Hanhhar tries to stop them. Mira tells the rest to go on, she'll take care on Hanhhar. Battle scene.
Basicly, LA pushed the game too much, and they couldn't finish the ending. But a good amount of this is still in the disks, so hopefully enough attention will come to it that LA will request a content patch. I don't care about the deleated planets, I just want a freakn' ending!
