They are able to build a BASE3, so I'm presuming they could do design changes to be able to produce a similar product to the current CAB2.
I'm sure this is really just the fact that they'd rather toss the ball over the wall and be done with any remote hardware. I get the fact that it's easier to change phone software than build a remote, it's just that the phone is not a suitable replacement for a physical remote.
On the bright side, they're still producing the CAB1L, and I use that a lot when running.
