I was in SEMA last November and had the opportunity to talk with the head of Toyota's marketing department for SUVs in North America and he wasn't very talkative about offering diesel SUVs to the US market. I asked him specifically about the Cruiser and he wouldn't elaborate.
Granted, this was three months ago and they're already popping the Sequoia. IMHO, this will happen one day or another, but Toyota will rather see how other makes fare in this segment before they take the plunge. And don't forget that the US now have the world's most stringent emission regulations for Diesels, and even a very diesel-experienced carmaker like VW finds it very difficult to have its next Jetta TDI 50-state compliant.
