On a side note, I heard on some forums that the TNI is evaluating the Swedish CV90 (possibly for pindad's IFV/Medium tank project), anyone heard that before?
Mindef already talking with Russia, Ukraine, Turkey, Korea, Spain, Sweden and Italy (some info talk about that to) on possible platform being used as based for the plan Medium Tank. Based on the info in media and local forum, Germany, Korea and Turkey got some serious follow up from Mindef and Pindad.
However Germany (Rheinmetall) seems going to get the contract. I've post this previously, and the procurement of Marder is the definite clue on that. Just like in the case of Anoa, the process begin with procurement of VAB, then discussion with Renault on possible manufacturing with Pindad, then Anoa is the result.
This pattern also being follow on with Sherpa (also with Renault) for Armored Scout vehicle. I do believe this is the pattern that going to be follow by Pindad and other local defense Industry for developing their product.
This is from Defense Media Center (Mindef On-line site):
Indo Defence 2012 : Kemhan RI Tanda Tangani MoU ToT Alutsista Dengan Brazil dan Jerman
Basically it's said that ToT agreement has been signed by Mindef and local defense Industry with Brazilian Avibras for MLRS and German Rheinmettal for (I believe) support on Leo 2 MBT and development of 30 ton Medium Tank.
It's more clear now, that Marder will be based for this Medium Tank. It will not be Marder (just like Anoa is not VAB), but it will be based on that.
