In PoA, (US, p205, bottom) Fudge says "And then, barely a week after the 
Fidelius Charm had been performed--" that Black betrayed them (meaning 
that was Halloween night when Volde lost his powers).  So we have the 
Potters only going under Fidelius a week before their death. and nearly a year 
and a half after the prophecy was made.

I say that Dumbledore kept it a secret for a long time until such a time as his 
"network of spies (same chapter of PoA) could inform him that the Potters 
were in danger.  
It would be risky but he knows all too well, that it is very tricky business to 
predict the future (end of PoA) and may have been resolved to keep the 
knowledge as secret as possible and let fate take its course.
