When will the market rally hit the 1 lakh mark?

With the S&P BSE Sensex a few hundred points away from the 50,000-mark, marketmen believe it's only a matter of couple of days for the 30-share index to touch the milestone. It took roughly 10 months for the BSE index to reach here from a low of 25,981.24 on March 23, almost doubling. Can we even have 1,00,000 in the visible future?
