If it's true, then maybe at Lipetsk, the Russian combat training centre.
Forget about this order causing a power balance shift... US announced this week that it will be supplying $30B to Israel, $20B to Saudi Arabia, $15B to Egypt, and also other Arab states, in weapon sales. Israel also gets additional US funding for air defense missile system development, announced last week. Saudi Arabia gets Patriot systems, JDAM, and AMRAAM. So far, there's been little specifics and no report of fighters, but I bet they will be included, maybe at the expense of the Typhoon deal with the UK.
It's aimed at arming the nations against terrorism, Syria (which is buying new MiG-29s) and Iran in particular.
I guess the US wants to be able to pull out of Iraq, and have Saudi Arabia and Egypt's support when Iran or Syria makes a move. And Israel, well of course, you can't supply Arab states with weapons wihout supplying Israel with more.
Anyway that's a different discussion.
PS: Don't forget that multiple sources reported a few years ago, that Venezuela would buy MiG-29s and pilots were already training in Cuba on the type!
