These people that say don't wait aren't helping you at all. My suggestion is look at the new features that will be incorperated into KT400, the most noteable to me is Serial ATA and USB 2.0 (some KT333 boards already have this, though), and since the bottleneck of most systems is the hard drive, this maybe a very good feature to have. I would hate to think that you buy a motherboard hoping it will be good for a year or two and in a couple months everyone is talking about how serial ATA is the way to go and you have to upgrade to get it.
