Remember, it has been said that Eberron is going to have a lot of update support online. So, what that probably means is that Eberron specific races already have builds because they were planning on releasing them before the release of the Eberron setting, long before. It does not necessarily mean that any of those races are core.
As for aasim- I mean, eladrins, I am guessing that the celestials are going to have the exact same change-up as the fiends. If you look human, you are an angel. If you don't, you are an archon. If they are taking away law and chaos as aspects of demons/yugoloths vs. devils and archons/angels, then I bet the current eladrins are folded into archons because of their dual nature. Trumpet archons, on the other hand, may get swiped by angels.
