I don't see this as becoming a regular thing for a very simple reason - the expense. This is costing them the extra work done by staff to handle, sort thhrough, and choose a submission, plus $160 total in "prize" money. Only then do they get down to teh normal cost of writing the things they'll actually sell.
Now, the hoopla surrounding this may well offset such extra expenditure. But that only works once. You won't see nearly as much interest in future settings produced this way.
