Quoted from pkiefert:

We will have some more available for sale in a few weeks. They sold much quicker than we prepared for and we are already waiting on the next signed batch to arrive, so we didn't feel it was right to keep taking orders until the rest that have already ordered have shipped.
I'll post here when we open it back up again.

Quoted from tonyoz:

They haven't sold the 250 yet, just that they are catching up on the orders that they have first and then will open them up again for what is left out of the 250

Quoted from pkiefert:

There will only be 250 of the signed and number translites available. We haven't sold out of them, just sold more than we already had signed so we are pausing sales until we catch up with the existing orders.

Quoted from Ericpinballfan:

Do we know how much game is going to cost yet?
