difference between 680i LT/SE and 680i?

What is the main difference between these boards besides the price? Does the LT/Se model have less features and overclock options, I would assume so but that's why I am asking. Also is 680i future proof by being 1333 fsb capable? I have seen some boards that are and that's why I am wondering. I am looking at possibly getting a 680i based board or possibly just wait for P35, haven't decided on that yet.

quad-core overclocking capability i beleive. I have my e6600 at 3ghz 1333fsb, its a 1066/1333 board so yes.
