doyles room is a part of tribecca tables. a few months ago tribeca gave all the sites a 6 month deadline to find a new software as they will no longer support US customers (and selling out). So playtech aquired all the sites that still want to take USA customers. the switch from tribeca to playtech will be any day know but most will be unaware as the sites will just tell all the players they are doing another upgrade. from what I was told they will mimick tribecas graphics.
I worked at doyles for years, I got all the good info.....any other questions?
