I think his WTF is from the fact that buying bulk for a later batch, is more expensive than buying individual for an earlier batch.  Given some of Bitmain's earlier statements with regard to how they price their items, this situation would appear to be counter-intuitive at best.  There's no stock indicators though, so if the March batch is almost sold out, and anybody wanting to buy a bunch of them is pretty much relegated to the June batch, then the higher price might make some sort of sense, especially with regard to lack of competition from the March batch.

In an unrelated thread somebody at Bitmain suggested waiting for a newer chip from them, have to wait and see what they produce with it though
