I can't imagine giving the Spurs an interest free loan on those tickets for 12-18 months, which is what you'd most likely be doing. Unless you have courtside seats that'll get swooped up quickly I wouldn't get tickets for next year and I'd request a refund for the remainder of this year. Besides, they're going to have to come way down on their ticket prices when they do open since a brutal recession and probably a depression looks inevitable. No reason to buy at the prices they ask for today.
