Anyone getting a Retina Mini, but buying an iPad Air anyway "just in case"?

Debating jumping on the iPad Air bandwagon tonight. I'd really prefer the Retina Mini, but depending on how true the news about "constrained supplies" are, I'm not entirely sure how that's going to go.

Best case scenario: Buy iPad Air, don't open box, buy rMini, return iPad Air or sell it.

Realistic scenario: Buy iPad Air, attempt to buy rMini, fail, keep iPad Air.

Worst case scenario: Attempt to buy iPad Air, fail, try again w/ rMini, fail, jump off cliff.

What are you doing?
