In addition it's the code base from Pocket Edition, aka the Bedrock engine, which is being extended and is going to be the base for the Xbox One X version in the Better Together Update, not the other way around.

In other words, everything they want to keep from the Xbox Console edition (aka the 4J engine), has to be reimplemented into the Bedrock engine.

Will most of it make it? Most likely at some point in time. Does most of it have to come in 1.2? Not necessarily, only that needed to make cross play work.
