WoTC is partnering with FoundryVTT to enhance it’s 5e game system. They will also be selling the revamped books later this year.
There is no overlap with DND beyond, unfortunately. More info at FAQ below:

This will be adventure modules and other official content to be purchased. Hopefully with all the bells and whistles you can have in Foundry.
Not sure if there is a big market, as most foundry users are comfortable putting the scenes together already.
