As mentioned by others, the plans as they have been mentioned by our CEO is to rework the game to the newer engine, which console is already using, with many features up for a rework and redesign.
This process will be done using the PC platform to be able to iterate more quickly than would be possible with just the console version. This reworked version will then also come to the console variants of the game so all clients are on the same codebase and version with the same content.
For our teams to be able to update the market place on console the game itself would need to be updated as well, which is not possible at this time due to the requirements for approval by both Microsoft and Sony. A short summary of the issues at play there can be found in Matt's "Tracking the Engine Upgrade" thread as well as the latest info on our way to upgrading the PC client which will then be brought to the console clients as well.
As for Crossplay:
Full Crossplay between the consoles and optionally PC is something that has to be allowed by Sony and Microsoft, but we are not planning for that.
Our current path is set on looking into Crossplay for the social elements of the game, not the action elements.
This was mentioned in the 2021 Roadmap.
