So after 21 million bitcoins have been mined, no more can be created.
As has been said many times before: 21 milllion bitcoins will never be mined, and new ones will always be created. In increasingly smaller portions, yes. But new (fractions of) bitcoins will continue to be mined, forever.
With the rise of asic mining, which will mine bitcoins 100-1000x faster than "normal" mining, at the rate asics mine bitcoins, we will reach that 21 million bitcoin mark way faster than the predicted year.

The title should be: the rise of asic mining, will it be the end of GPU mining (and the answer is: yes, just like GPU mining was the end of CPU mining).
As for Bitcoin itself, it will only flourish more thanks to asic mining as it merely strengthens the network further.
