how will the BCC fork happen? fill the block with fake tx?

we are past the timestamp now and in the fork territory, but the question is how will the fork happen? is there any place to monitor it?

because in order for this hard fork to happen they have to build the first block after this time with more than 1 MB size.
the problem is that the transactions that we are currently making in bitcoin are invalid in bitcoincash! and there aren't anybody to make any bitcoincash transactions. people are still scared of downloading their wallets which are signed anonymously.
and also most of those who understand it, are first wanting to move their bitcoin and then import the private keys there!

so there is no tx on BCC, how will it reach 1 MB? even if they mine a block with low hashrate after hours and still don't reach 1 MB+ they have to reject it and mine another for another hour!
