The aircraft that you have show on this thread is the MRCA demonstrator 154. Would you care to explain how this very aircraft is still on MiGs inventory. Here is the very same aircraft pictured in Russian in 2004:
Here is 154 in its new livery during 2005: 
Individuals like yourself are naive enough to believe the idiotic rumours that abound. In reality to date Venezuela has no MiGs in its inventory.
I agree the one shown in my pictures are the demo,
But I know sources In Government in venezuela,
specificaly Maracaibo, which have in fact seen the new Migs The Squadron is even already being assigned the same designation as the old F 16 squadron. (which was called Squadron de casa,or Hunter sqaudron!
Cuba and venezuela Are Training together Where Cuban Pilots are the Instructor. This is No secret, The Planes are on an Airbase In Maracaibo, which is the closet base to The Panama canal(which the Venenzuelan General stated the purpose of the migs were for which was to Protect the Canal) US militay operations in the island Of curacao Have observed the planes also, Once again it is no secret!
whether they have the 50 they ordered I dont know but from what I know They have at lest 6. 2 trainers and 4 operational. Russia is supplying Venezuela with all kind of weapons, They even Have the New AK 103,104 to replace the older MAS FAL rigfles. Not only are they getting the riffles but they are opening a factory to produce them under factory patent. Also no secret!!
The contract was sign in 2004, and they are now receiving the firearms and the some but not all migs are there,including a chinese spy satelite,and brazilian made light attack aircraft.
VEnezuela has the means and the resources to take on the US, but will ut ever happen NO. Because the middle class in this country will be pushing their cars for a long time to come if that happens.
