If you see many comments by international players, and those on the domestic circuit, I don't think you see that Tests are always considered the 'top level'. That's what is so worrisome. People think being a IPL/ODI star is the peak of their achievement. If you make more money in ODIs, get more endorsements, see more response from crowds, and see it as the centerpiece of selection and touring, the perception of Tests being the highest level of cricket will not last. Everyone wants to wear the blue, not as many dream of the white.
The end of Test cricket may not be nigh everywhere else, but I fear it may be so for India. I am not saying that they will stop putting out Test teams, but two Test series and players being rested or pulled out so they can play more limited overs cricket, or players retiring from Tests to focus on the shorter stuff, all that is upon us.
