Yes...it'll be across their platform. They're pulling out and changing an entire module to accommodate this. This is the entry point for Adobe to transition and add content replacement in future iterations. Once you've isolated the masking to a controllable function, the next step then simply becomes, content replacement... Replacing skies or removing objects becomes easy.
Glad to see Adobe responding to all the recent editor's with all their AI and replacement features...
Please I don't want to start a flame war on the artistic merits of image alterations into something that never existed... but in many cases, it's nice to have the ability to make these types of changes.
