I agree, india is going to be big. Though the guy just mentions it without backing up.
I was told that people from different area would rather talk english than hindi in communicating with each other. Probably more so in the educated class.
Any one from India can tell us:
1. How big a population speak Hindi native?
Hindi: 180M-500 million ; Tamil:74 million
More than 180 million people in India regard Standard Hindi as their mother tongue, making it the fourth-most spoken language in the world. Another 300 million use it as second language. In the same wiki page, there are also data of 500M native, 800M uses (some variants of) hindi.
Wiki Source as hunted down by OldIDNer:

2. How many years of Hindi lessons nonHindi speakers get as opposed to english?
3. Is english one of their official language? how prominent is it as opposed to Hindi?
English is the associate-official language.
4. How easy is it to type Hindi from keyboard?
Should be pretty easy.
5. drbiohealth cites the news of the first search engine devoted to hindi, multilingual maps and mobile games.
All happening in the last few months. This is going to be interesting

But I think Indian action will happen
a bit later than the Chinese action (maybe 1 year delay)
6. What is the biggest online Indian news site in Hindi vs english? I'd like to look at its alexa traffic, though alexa
traffic is admittedly unreliable. Chinese internet companies take alexa seriously, too seriously, so that could easily
distort the data.
