As long as they are allowing both new races to be Death Knights there is no reason the normal, non- "heroic" jobs should get penalized for an achievement that a DK can bypass the first 60 levels of.

So disable DKs for the new races (for the first week), too :P

"So disable DKs"

Fixed.

I daresay they will disable Death Knights for the two new races at first - we're already swimming in Death Knights. They'll probably put off implementing that until the people who start at level one have a chance to get up to 58 themselves (on average).

Who cares? Why are you so worried about L60 goblins/worgens? I couldn't give a toss if other people want to spend every waking minute grinding new races if that's how they get their jollies, doesn't affect me in the slightest.

IMO they always should have made it so that you could only make a Death Knight if you had a character of that RACE over level 55. Would solve the Worgen/Gob DK problem at launch, while still allowing players to have DKs of these races by getting another class up to 55 first.
