I earned Platinum for 2010 and 2011 but come 29 nights short for 2012. They let me keep my status anyway as a courtesy. I wasn't worried, though, because once you're Platinum, you can keep it forever really. All you have to do is pay 40k points a year to keep your status. The hard part is earning Platinum once, but once you do, you're pretty much good to go for as long as you ahve 40k points to cash in.
