Has it been decided yet if that Wetek Core Air Mouse remote will be available to buy separately, and then use on the Hub?

That is a question for WeTek themselves to answer.
IMHO, the Core's RF Air Mouse remote (or similar) should be offered to end customers the day the Hub is released, as a extra cost purchase.
Otherwise I expect a bunch of frustrated and potentially unhappy Android users.

BTW: This Air Mouse issue, is the exact reason why MINIX offer up a number of different remote control options for their Android devices.
WeTek you NEED to respond to this remote control question and detail what you intend to offer to customers.
