We are thinking of releasing the QT wallets already to have some sort of mining competition.

The last PoW block is 10000 and we are now close to half way there on the blockchain (we have mainly run it with PoS and not PoW but we know it is working correctly).
The block reward is 48WWC and the blocks come fast, every minute. So there are about a quarter of a million WWC available to be mined before the last PoW block (worth around $200k at ICO prices).

I think the safest thing to do is to release it as a PoS only coin after the PoW blocks finish unless anyone has any other ideas ?
