This is subject to exchange confirmation, so it is subject to change.
cross-post from Slack
@teckii2 I see you have a count down clock - please remember the announcement we made yesterday needed the exchange to confirm. The effort and process from our side is now ok and tested, but we need the exchange to be 100% confident with everything on their end, in particular the allocation of people resources to the whole process to match all the coins against many, many accounts.
So please do expect we may have to alter the block height once all parties are in complete agreement.
We have given a block height because we want everything to happen as soon as possible and that was our indication that we want it to be sooner rather than later. The timing is an indication that we are narrowing down to launch.
