“We are talking primarily about providing our forces with state-of-the-art modern technology,” Putin said at an air show in the Moscow Region ahead of the 100th anniversary of the country's air force. “Over 600 new warplanes and 1,000 helicopters will come into service by 2020 – not mentioning the upgrade to already existing systems.”
(I found no much more reputable sources so far.)
Russia's nominal GDP is USD 1,850 billion according to wikipedia.

The figure of 600 new warplanes is furthermore much greater than the earlier figures for planned PAK-FA procurement.
I see three interpretations, in order of descending probability:
(1) That was a wrong report.
(2) Putin is a loudmouth.
(3) This is going to be a full-blown air power (catch-up) arms race.
