They've discontinued the current production run; according to the BPL OR show article, TNF is bringing it back with what appear to be some minor modifications:
"Of the more interesting rain jackets on the market is The North Face Diad Jacket. TNF announced some modifications for it that will appear in the 2007 model to both clean it up and improve its performance. For 8.5 ounces, you get rain jacket with a tremendous fit (well-articulated, excellent adjustable hood, mid-length hem, long enough arms), welded seam technology, core vents, chest Napoleon pocket, dual handwarmer pockets, 2.5-layer fabric, adjustable cuffs, and a drawcord hem. Where on earth does this product save weight? In its remarkable 15d fabric, branded "HyVent DT" (note the similarity to the excellent Entrant DT fabric, which has breathability rivaling eVENT). Unfortunately, TNF ruins the photography experience with its reflective logos. Regardless, this will be a jacket to watch for in the coming season."
I prefer to take the 62.5% price reduction though by buying it now!
Meanwhile, Google has preserved the old TNF page:
