We (ypool) will continue to support the old PTS as long as people are actively mining and trading it. Additional we are currently considering to lower the amount of confirmations needed to speed up the confirmation time for users. At this point I don't know how far we can reduce the time since it means that we have to pay miners in advance, but something like a 50-70% reduction would be nice.
Regarding the PTS-DPoS snapshot we did for our pool PTS balances: Instructions on how to redeem the stake will be posted within the next few days.
