Great to hear some good comments from gurus here in the forum.
The latest updates are
Some issues in E block related to Bait ul maal.
Land ownership issues in D block.
B block prices are already sky rocket.
I think you have got a good option of investing in C block as the prices are within the range because of the market is on a still for the last few months so you will get a good plot at a reasonable price at this time.
You have to wait for sometime to let the sector develop but I visited B block and many houses are built in this sector along with some shopping malls already constructed and few were near to completion.
I can perceive a very bright future for B 17 as heard from someone that MA is likely to be completed by Jan 2015, so it's a good move...........
