Klingons in Star Trek 2?

Rumors abound that the Klingons will be showing up in the sequel to JJ Abrams' Star Trek, which hits theatres in summer 2012. In an interview with IGN, creature designer Neville Page addressed that possibility and discussed ridged forehead and non-ridged forehead Klingons.
On the latter issue, he says, "It’s almost like treating it as if I were a Klingon designing the human race. How would I go about it? And then I think about it from the perspective of an alien looking at human beings: some are lighter in skin color and some are darker. But you would go, those people with their eyes with that flap of skin there and then those people who are really tall and sinewy. But there are different physiological ticks even in the Klingon world. Maybe they are all brown, but the ridges are the African ones, the fewer ridges are the Asian ones. I don’t know, but I always feel the necessity to justify and rationalize even if I can’t actually. It just gives me something to work from.

"My approach [in the sequel] would be to try and come up with something that’s a unique look but is still a Klingon, obviously. Because I think if I did them really tall like say 9′ and instead of brown made them blue, I might get into a little trouble! But I would try think about them as real deal people — and I know other designers have — but really give them a history and a motivation. Understand why they’re dressed the way they are. Understand their rationale for long hair and facial hair. Make sense of those physical features which they typically have, which are the ridged foreheads."
