The first offers for 2018 would be August/September to start Jan 18. We all knew that until then it would be quiet. The fact is that if at the moment SH is correctly crewed this does not mean in 2018 with new aircraft being delivered and more part time/commands that it will stay this way. At the moment people are looking at tea leaves.
The last communication from BA to the hold pool was that 2018 will be a busy year for recruitment on SH and LH. Even if they only take 120 guys that will be a large chunk of the hold pool.
As FACoff said, I hope that BA will update the members of the hold pool even if it doesn't contain anything we didn't already know.
On a side note, surely in this day and age of cost cutting the guys would be kept in the pool regardless.
