The reality is that the FMM will have ports for 1link and the flow sensors. This is one reason why I think this thing is delayed. They decided to put it in the bar. Same with people who might have bought the WAV package. Talk about a waste of cash now for them. But I see the argument. If something goes wrong and you are taking advantage of what that new bar has to offer, you could lose any low voltage hook ups, your WAV's if you have them, and I suppose the DOS, although you can hook that up with Aquabus anyways so life would go on there. At the moment, the lineup is fragmented. A little here and a little there. It's fine for the first time buyer, but anyone switching over, or wanting to mix and match, there will be redundancy, and some things that just won't make sense.
