FFS planning to publish any more Adventures for AoR?

Yes

Any insight on when we might be seeing some news on that?

I really can't say.

The property is popular (and will likely be even more so after Rogue One hits theaters) and the license is, presumably, lucrative. I'd expect that all three product lines will continue to see support for several more years, at least. I've not seen any third-party publishers putting out material - it may not be possible under this license - but there's several fan-made supplements & material out there, including updates of the old WEG modules.
