What exactly would prevent the new algo from having an ASIC developed for it? Surely it's impractical to fork every time ASICs come on to the scene?
I'm all for forking, and people starting projects to work on but I think keeping the name will cause confusion and hurt Litecoin rather than help it.
Litecoin will keep it's name. After the hardfork, Litecoin still is Litecoin, nothing changes except for the algorithm.
Some people may stay on the old fork by not updating their client but it will die soon as no exchange or pool will except it.
No large pools will follow you.
