I think elves are gona have a resolution when Tyrion/Malerion come out.
Considering that Hyish is the plane where the Swifthawk HQ is, i think Tyrion Aelves will have the traditional High Elf looks but with a lot of movement (see namartis for s good example of what i mean). The whole "angelic" deal may be refering to grace and beauty, not the whole "wing and halo" thing.
I also believe thata lot of elf plastic is gona be absorved into their lines. Swifthawk, Draconis, Phoenix, Eldritch Council and so on, beeing renamed, just like "gloomspite" were.
Until there no BT for us...
