Freestyle has been a very successful marketing concept, mostly for Coca-Cola. Less so for the stores that adopt the machine. It isn't exactly driving traffic into the stores like Coke had promised. They've also had a slew of maintenance problems.
Pepsi has had time to catch up and has recently launched Spire, their multi-flavor machine. They chose a simpler approach and skipped the whole microfluidic flavor cartridge thing. It's simply a revamped fountain/flavor dispenser with a new interface. It works just as well as Freestyle IMO, and actually has an advantage of using less physical space up front (but still needs the whole syrup stack behind the scenes)
