In my personal opinion (may be wrong), with a huge supply of material (20,000 plots), lack of actual buyer's support and near future addition of further plots will the push the
prices downwards.
It is difficult to manipulate and play with prices of such a large supply without substantial real buyers support where almost 90% are traders and very less numbers of actual buyers. Every balloting is just adding more traders looking for profit.
Prices of all phases may come down due to the same reasons mentioned above.
Above all, any political crises (due to judicial commission or any other reason) will make things worst. I have been observing the prices since 2011 and noticed the major change (200 to 500% increase, bubble) just after NS came into power.
This is just my humble opinion and if anyone is saying that plot prices never came down he is not well aware of the history. One should see what happened near 2007.
