It seems unlikely to me. You already have a 2 out of 5 year rule, and that should give you A LOT of flexibility. They did not extend it when the housing market was REALLY bad in 2008-ish (actually they tightened it up a bit). And according to my real estate agent, my area doesn't look too bad.
If you are worried about meeting the 2 years, DON'T wait until the last minute.
