Seems Pindad looking to South Korea for IFV based (potentially) on K-21. If you look at this :RI-Korsel tingkatkan kerja sama industri pertahanan - AntaraNews.comWhat IFV prototype do you mean, Ananda?
The latest talk between Indonesia and South Korea on Defense Industry cooperation. besides existing projects 209 SSK and T-50, they also talk about other projects including what they called 'joint development of medium tank' project.
Again, this Medium Tank project (IFV) is what Pindad aim for future and not MBT. Any tech they can gain from KMW is just to strengthen their Know-How for IFV project.
It's still early but what I emphasizes is, from all indication IFV (Medium Tank in Pindad term) is what Pindad after and not MBT.
For the current Prototype, so far the only Pictures available is the 'technology prototype' that Koxinga has put on his post no 181 in this thread. Local forum and Pindad development (like the possible projects with South Korea as mentioned above) indicating that prototype is only Technology Project from Pindad and will not move on to Manufacturing Phases.
Perhaps I'm a little bit hasty calling that prototype as IFV prototype. However since most IFV in the market derived from APC, then perhaps it can be called as IFV prototype
