That's assuming an awful lot. We still don't know where these three came from; they might have only shown up after Malak's death.
And I hardly think they'll make these three weaker than Malak, given that by the end of the game we'll be stronger than Revan. Where's the fun in that?

This brings back the eternal discussion. Do game mechanics have a meaning storywise? I don't think so. Granted, the PC will be level 30-40 at the end of the game, but that doesn't mean the PC will be twice as powerful as Revan was at the end of K1. That's absurd. Revan was supposed to be an epic character, and I'm guessing the new PC will be as well. So was Malak, but again, having a PC that by the end of the game would be able to mop the floor with Malak makes no sense storywise, since it would be so anticlimactic. And since Revan had 5 years to become more powerful, I doubt the PC will be more powerful than him/her (that's assuming Revan's still alive).
In any case, Malak managed to keep the Sith united under his rule, and it was a rule by force. So, unless they give a pretty convincing explanation, it makes sense that the new 3 Sith lords stepped forward to fill the power vacuum left by Malak's death. If that means we'll be playing a less powerful character than Revan was (again, from a story standpoint), that's fine with me. But no way I want TSL to follow the EU tendency to get more and more powerful characters each time. Enough is enough.
