Ah ok, I thought it was when Rebecca is dead.
I cant remember the other ending all that much, but I can remember Rebecca getting shot at one stage by Wesker.
Anyway, I think it is time that Capcom release another Trailer for RE4 and some more news... because I'm loosing interest in the E3 Trailer that I've watched about one thousand times.
As for the second playable character in RE4 apart from Leon, I think that it would be somebody new into the storyline... unless it plays out like RE: 3 Nemesis with just one character account but numerous swapping over... but I guess then that would have low replay value.
Oh, and to just clear up all the REmake Endings... here they all are:
---JILL'S ACCOUNT---
-Save Barry & Chris
-Kill Barry & Save Chris
-Save Barry & Kill Chris
-Kill Barry & Kill Chris
---CHRIS' ACCOUNT---
-Save Jill & Save Rebecca
-Kill Jill & Save Rebecca
-Save Jill & Kill Rebecca
-Kill Jill & Kill Rebecca
