Mirage2000-5 and its variants

All the latest aircraft seem to have been discussed in here and the topics flogged to death.But one aircraft – the Mirage2000-5 and its variants don’t seem to have been discussed in detail or exclusively in here.
With India in preliminary discussions to buy the latest variant according to the defence minister in parliament itself, how about a discussion on this aircraft. We all know that the IAF loves its Mirage2000’s. How big a jump in technology is the Mirage2000-5 over the current IAF mirage’ s. Whats the latest variant of the Mirage2000-5 is it the Mirage2000-9 or is the 9 a UAE specific aircraft.
Well it has been discussed that it dosent make sense for India to go in for the Mirage2000-5 when it already has the Su-30MKI. But is it feasible taking into account that the IAF dosent want to put all its eggs in one basket and the fact that the IAF intends to increase its No of squadrons to around 55 rather than seeing it as a replacement for the Mig-21’s and 23’s about to be phased out and till the LCA finally roles out.
If the IAF decides to go in for it(or should I say the Government of India- the poor IAF dosent seem to have much choice in decisions taken these days) what role will the Mirage2000-5 play in its doctrine. How will the Mirage2000-5v stack up to the aircraft around and those in its neighbourhood and those being inducted.With China geting more and more SU-30MKKS how will the Mirage stack up against them.
All in all what configuration will the IAF be looking in the latest Mirage2000-5 variant. There has been talk of technology transfer and the setting up or selling of the full production line to India. Keeping this in mind should the IAF go in for it? What about the price factor.
Will the Mirage be using components from the Rafale? What armament will it carry, what will the radar and avionics be like. What advantage will it give the IAF keeping the future in mind. Should the IAF go in for it or wait till a latter and better version of the Rafale is out.

Cheers Guys!!!
