Yes, i think so there wouldn't be any reason to not releasing them. The trading must start, because the sale has ended. Otherwise it will be a problem for the coin makers.
Exactly they will release once the ICO closes so that we can have liquidity on the xchanges, unless your asking some other question but that seems to be the answer. Seems to be the case across all ICO's and i'd imagine theirs more detailed explanation when you check the whitepaper.
