It isn't anything new, it is the same stainless-steel locking mechanism they have used for years. My old Glide 2000 (circa 2000) and Glide Tech Pro (circa 2001) have got the same system on it. Granted, it can be a bit of a faff if you keep moving from, say, a 12-litre to a 15-litre, as it isn't as quick to adjust as the normal camband systems, but set it up right and really lock it into place and your cylinder isn't going anywhere. I do around 300 plus dives a year wearing these jackets and not once have I had my cylinder come loose. You do need to make sure it is tight as it cams into place, but once this is done, it is far more secure than a normal camband, as far as I am concerned.
The T-Force is a nice jacket, much like the old Glide 1000 or 2000, and basically is a new design to fit in with the T-One, T-Sport and T-Black range.
