If there ever was a hard fork of BTC I hope they'd include a POS system, but hard forks seem to only be done out of necessity these days.
I've been reading up on it... Some of the altcoins start as POW, then slowly switch to POS as more coins are mined. Then there's NXT, that is pure POS. Somebody's got to give you some coins before you can start mining or "forging" as NXTers call it.
The Bitcoin community seems unaware or apathetic to the impact that ASIC centralization has had. It has re-created the "1% vs. 99%" scenario...
