The new Austrian govt decided that it wanted to pull out of buying Typhoon but then changed its mind when the cost of doing so was pointed out.
AIUI, they compromised so that they now receive some Tranche 1 ex-Luftwaffe aircraft. The Luftwaffe is happy, since it gets the Tranche 2 aircraft that would have gone to Austria and ends up with about a dozen newer airframes; the Austrians are happy since they don't spend quite as much and Eurofighter is happy because they sell the aircraft. Or something like that, anyway.
