I highly doubt there will be any support for X10. The biggest issue with X10 is confirmation feedback.
For example, if I am in my kitchen and I use an X10 remote to turn on a light in the garage, I will have no indication that the light is actually turned on. The best guess would be to press the ON button on the remote 100 times so that you can be reasonably sure that at least 1 of the 100 turn on commands made it through to turn on the light. But still, you won't know for sure because the X10 technology does not have the ability to report its current on/off state.
Some years ago, I did read about X10 version 2 that does have confirmation feedback. But I guess it really never caught on because I've never heard any more about it. And I also lost interest in X10 technology.
