Probably the same reason why you can't preorder the Xbone x. No FCC.
Who knows though. Glad to have locked in internationally already.

Because there is no FCC approval yet, Microsoft and its retail partners are not offering the Xbox One X for pre-order.
It is out of Microsoft's hands when the FCC approval will be granted. The Xbox One X announcement was on June 11. An FCC approval doesn't come through in a matter of days. It is weeks and possible months. It is likely the same situation for Nintendo. Therefore the pre-order for the SNES Classic will at the earliest happen end of July.
A wide ranging pre-sale of the SNES Classic might also not happen at all. The pre-orders for the NES Classic were only available briefly at a few stores including Target, ToysRUs and Amazon.
