In this case thats not even the deal, they are not offering a pre-sale given the hassles from the rokstock. Its their customers asking for one.
I get the notion of wanting to get your name on a list (pre-order) what I roll my eyes at is any retail customer thinking it benefits themself in any way to pay for an item that does not yet and may never exist as a consumer product (pre-sale).
