I've missed it if they've said they won't have voice skipping at all. Every previous bioware game has. Or at least every recent one.
As for MMOs having an end, I think they were talking about class arcs, not the game itself.
People need to stop thinking about this game in terms of EQ or WoW, maybe. That's thinking too small. If they start with everything they're advertising, they're going to be several magnitudes larger than any MMO has been at release to this point.
