How many times MoD has changed their decision after trails are over and deals are in final phase? Delay in artillery modernization program and recent scraping of airbus refueling tanker are examples. So lets see what comes up after the deal is signed.
In both examples it wasn't MoD that changed things, the one ended in a bribery case and the other one was rejected by the finance ministry, IAF and MoD cleared the A330 tankers!
Have HAL declared the engine for LCA-MK2? I do not think the deal has been finalized. I do not want to count my chicken before they are hatched. HALs track record in meeting deadline is well known. So, as of now, 40 LCA for me. When HAL is ready with first test flight of LCA- MK2, I will talk about that.
No the evaluation is still going on, but the RFP that was send to both engine makers was for 99 + 49 optional engines, so the least number of LCA Mk2 is officially 99:
...The companies have until 12 October to respond to the request with information on their respective F414 and EJ200 turbofans, with New Delhi looking to buy 99 engines and take an option on another 49...

If any platform fires the same weapons are they same? What about the radar, airframe, avionics, range, and weight etc? By replacing if you mean replacing squadron number then you are right. But SU-30 MKI is altogether and way above mig27 and mig23.
See in the past Mig 29 was our main air superiority and the Mig 27 our main ground attack fighter, especially for heavy stirkes. But then multi role fighters arrived and the Su 30 MK is the multi role, strike fighter version of the Su 35 (Su 34 is a dedicated bomber design, specially for Russian needs), similar to the US F15 Strike Eagle!
The MK offers a lot of payload, range, weapon stations and more important 2 pilots and a big variety of A2G weapons, that makes it very useful in this role and why China bought it in addition to their single seat air superiority Flankers.
So to replace Mig 23 BN and Mig 27 ground attack fighters, the MKI is more than useful, even these are only its secondary capabilities, besides the main air superiority role.
It is wrong to say the one is more capable and that's why it can't be a replacement, because you forget the evolution in fighter development. All 4 - 4+ fighters are clearly more capable than older gen fighters and all 5. gen fighters will be more capable then them, so that is not an argument.
LCA when it comes by 2012-13 will replace existing mig21 and BISONs. Again MRCA (which plane comes) would be much capable than Mig21 and BISONs. Agree due to the delay MRCA is coming in. But it was never supposed to replace mig21 or BISONs. It will enhance the fire power of IAF .
Let me explain the last post more detailed, LCA was supposed to be the replacement for all Mig 21, that's right! But due to the delays in development, IAF/MoD don't wanted to rely only on LCA, because of the shrinking squad numbers. That's why they wanted the first MRCA competition to replace at least a part of the Mig 21 faster and with a ready and proven fighter.
The initial contenders was similar light class, single engine, interceptors just like the Mig 21, or LCA (the Gripen C/D, Mirage 2005, F16 B52) and only the Mig 29SMT as a double engine fighter. Even these fighers were clearly more capable than the Mig 21s, but are used mainly in the same intercepter role.
The only reason why we now have even more capable and mainly medium class fighters was, that Dassault replaced the Mirage 2005, with the new Rafale in the competition, which was followed by offers from Boeing and the EF consortium for F18SH and EF, so a totally new competition was needed (the M-MRCA).
The aim of IAF/MoD is still the same, replacement of a part of the Mig 21, but the capabilities of course increased clearly!
Around 125 Mig 21 was upgraded to the most capable Bison level and will remain in service till 2020-25 at max, pretty much the same number and time frame that is given in MMRCA!
Replacement in numbers will most likely be like this:
Mig 21 Bis/M/MF (around 145 fighters) => 20 - 40 x LCA MK1 and at least 99 x MK2.
Mig 21 Bisons (around 125) => at least 126 x MMRCA
Capabilitywise, the LCAs and the upg Mirage and Mig 29s will form the low end in future, while MMRCA, MKI and 5. gen fighters will be the high end.
