There's no mention of pricing. The inclusions of both a 4K screen and Thunderbolt suggest that the XPS 12 won't be cheap, but the cost will depend on both the choice of processor (a Core M or low-voltage Core i seems likely) and the amount of built-in storage. However, there's no question about availability: the leak hints at a release in October, right when the Surface Pro reaches Dell's corporate sales channels. While it's doubtful that Dell built the new XPS with its Microsoft partnership in mind, it'll conveniently serve as an alternative when you want a little more oomph from your pro tablet.
