Both the new Bally and IGT games are equipped with SAS technology which allows them to use either the IGT or ACS TITO systems.

It is unfortunate that at this point, much of the more popular games many of which are manufactured by WMS [Williams Gaming] are being removed. It is my understanding from what I have been told that they do NOT conform to the current TITO systems.

WMS did unveil a slew of new games at the recent gaming expo. I do not know however if they will be compatible with the technology required to have them re enter the market they seem to be losing.
From what I understand, there are some other issues with Williams gaming regarding bill acceptors but I believe those issues have been dealt with.

If someone is versed in this, I would nbe interested in finding out.
