HTTP 1.x will not disappear just because 2.x is available. Millions of people still run wifi networks on 802.11b; all those routers still keep on workin' even though 802.11a/g/n had 'sufficient benefits' that we build those into new hardware. There was no massive undertaking to replace all the routers in the world.

Nobody would have to change their old apps or hardware. Like SPDY, the availability of a new protocol supported by web browsers just means new stuff can optionally do things old stuff can't.
