LOL. The stresses were a bit weird at times, but I think that's more the fault of the language transition than anything.

Also, C.C. doesn't sound near mysterious enough. No real opinion on anything else.

I am amused that they chose to have the mindfuckery bits in the trailer. Inexplicably, naked people! (specifically, naked Lelouch and Suzaku, lol) Also, a bit spoilery, but that's speaking with hindsight.
