Compared to other bikes in the XC race category, the Zaskar 100 geometry is odd. The chainstays are long, the top tube is short, the head angle is slack. Given those numbers, I would not buy one of these without a thorough demo ride. Or...I might be willing to bank on a few credible reviews, credibility being 1) The reviewer hasn't already bought the bike, and 2) the reviewer has spent time on other comparable bikes. Unfortunately, as others have said, there are no such reviews.
GT's marketing strategy seems to be to hoping we'll be seduced by the sexy curves and a "smokin' deal" from Performance or a web dealer.
