The Mahindra / BAE JV was scrapped and Mahindra bought back the BAE share and the KMW / Ashok Leyland JV was more for a licence production of the complete package, that's why they showed models of the PZH2000 or Donar, rather than a truck based version, which so far was not even realized with German trucks, most likely because the gun module is simply too heavy for a 6 x 6. I'm not even sure if that JV is still on, since there was no news on that since 2012, neither from the Indian nor the German side, while the recent reports suggest that Ashok Leyland has teamed up with L&T and Nexter for the CAESAR, so I wouldn't bet on the old JV's anymore.
The possible JVs back then included...

And the recent proposal of KMW for their Donar / AGM howitzer as a wheeled alternative was this:

Which then also would be the likely offer to India now, especially since we have tested the same gun in trials in India earlier, based on a Denel G6 platform, which was heavier than many of the currently proposed tracked howitzers.
I still think the German gun is the best choice for us, but it's unclear if it could be fitted on a truck, especially on one of the Indian trucks that are available at the moment.
