I had a small number booked in yesterday, obviously not enough to clear back-orders.
MSI updated me this morning and based on that update the next lot won't leave the factory until mid July due to PCB supply problems. At which time we've got another 100pcs coming direct from the factory, so we should, again, get our stock before anybody else.
This is what customer service looks like. Factual and to the point! Thanks for the update.
