Asics can't be redirected to different alt coins that have a different proof of work. They will run to recoup the costs. That is why bitcoin will be more secure even if prices and transactions drop from a move to an alt.

Miners are playing a game of chicken to milk the fees while hoping users don't swerve to another chain.

Some Asics can mine both Bitcoin and Lightcoin though not at the same time. From a cost perspective they are slightly more expencive, but miners could swap over 2 years to a new coin with minimal issues limiting their long term risks.

I don't see an altcoin beating out bitcoin soon, but if one started gaining traction it would probably have a proof of work system compatible with most miners' asics.
