Let's do some quick math:
Since '99 the format on WNEW has lasted 1204 day for one instance (Hot TalK), 359 days in another instance (Blink), and then 737 (Mix). This means that mean shelf life for a format at 102.7 for the last 8 years is 766 days with a standard deviation of 345 days.
Which means, statistically speaking, that there is a 50% chance that 102.7 will have a new format in as soon as 283 days or as late as 1249 days. So, I'm willing to bet that sees 102.7 flip between September 2007 and June 2009.
***note I am using Chebyshev rules to determine the 50% probability, if this data is normally distributed (we'd need 102.7 to flip at least 50 times to see) then the odds shoot up to like 80%, in that case the 50/50 line gets much closer to Mid-february 2009. In fact, I'd be willing to make a market where I have the timespand between November 2008 and June 2009.
