http://www.thehindu.com/sci-tech/india-to-go-alone-with-chandrayaan-2/article5022717.ecePersonally, I feel that with the inevitable delays, it would be better for India to instead use GSLV-Mk3 for the next mission to the Moon. This will increase the payload envelope, and allow for a more substantive payload to be sent, with appropriately increased mission scope.Let the Mars Orbiter Mission be the last PSLV to send a payload beyond Earth orbit for ISRO. All further missions beyond the Earth should at least use GSLV-Mk3, or whatever more powerful successors show up.

The GSLV's first couple of launches were successful but after that it's performance went down the drain. If the test flight of GSLV-2 is successful on monday it would make it the ideal choice to ferry a follow on mars mission.

Looks like Chandrayaan-2 is falling short of funds:http://economictimes.indiatimes.com/news/politics-and-nation/isro-awaiting-government-nod-for-more-funds-for-chandrayaan-2/articleshow/24946130.cmsGuess a lot will depend on how Mars mission fares in coming time.

This is the first I'm hearing of a second ISRO Mars mission. It's not there on the Indian launch schedule sticky thread - which goes so far as to manifest a manned spaceflight for sometime after 2020 - so I don't think ISRO's ever mentioned it.
The Chandrayaan-2 mission seems to be languishing due to the non-availability of the Russian lander:http://www.dnaindia.com/scitech/1868557/report-india-s-second-moon-mission-chandrayaan-2-stuck-in-limbo

There seems to be a followup mission on the cards (2018!!). Here (towards the end):
"In the meanwhile, we found that it was feasible to develop a lander indigenously too, within three years, so Chandrayaan-2 is possible by 2016. The rover is already developed, the lander can be readied in time. All we need is the green signal from the government and at least two successful GSLV flights,'' the chairman said. “It was not planned as a completely indigenous mission, but it may turn out that way. Chandrayaan-2 will therefore be much more ambitious than its original aim.''

The Indian Space Research Organization (Isro) is planning to launch India’s mission to the moon, Chandrayaan-2, by 2016, which would include an orbiter, lander and rover, an Isro spokesperson said on Friday.
“Chandrayaan-2 would be launched by a Geosynchronous Satellite Launch Vehicle (GSLV) powered by an indigenously developed cryogenic engine,” said the Isro spokesperson.
The 3 year timeline was also in part to ensure that GSLV has a had a couple of successful launches behind it before it launches something this valuable. Again, it depends..ISRO needs to really deliver wrt the GSLV program. And also the lander design fabrication testing going well. The 2016 target indicates the shortest possible time for the launch of Chandrayaan-2 if everything goes as planned.
