I don't think army is going to buy MBT-2000 for replacement. ( old stuff, specially considering our next gen tank will be in Service for next 30 years )Like I said before most of our tanks with 125mm gun are Type-59s and they are old. Sooner or later we'll have to replace them. Also our LCTs can carry max 48-50 tons MBT. Since we already bought light tanks from China and trying to diverse our source from that country if army don't buy any new MBT-2000 in future then Type-10 could be an option. After what we saw happened to Russian tanks in Iraq and Ukraine (and other areas), modern tank is necessary besides human development. If a tank can't survive enough in fight what's the point of having skilled crew?
As I said before, MBT-3000/VT-4 is within our reach in terms of cost, ( around $5 millions per unit ) weight (50/52 tons ) and easy operability.
As we saw with the procurement of VT-5, ( $3.5/4 millions per unit ) army is now ready pay some extra for up-to-date state of art assets, we can logically assume our next likely choice for the replacement of type69 and type 59 would be VT-4.
