Quoted from KevinCPR:
To produce the playfield you signed up for within 12-18 months of the Inbox opening - not 3-4 years anymore.
This is a big plus for me - I was originally in on the FT ones (main and smaller), but after a couple of years my tastes changed and the machine was 'traded' off for something else. I think if anything, the wait is what caused people to drop off the list.
All the best with this new system - and I still look forward to 'hopefully' ordering something in the future.
