To me, it seems more like a statement than a question. They're saying that in addition to the cross-platform version, there will also be a own version for PC. The original, or "Minecraft Bedrock" as they call it, the one thats not for Windows 10. I thought the Bedrock version was the one for Windows 10, the one thats cross-platform.
You're a bit off.
Minecraft on systems that won't get the Bedrock engine will be labelled with their appropriate platform name, like Minecraft: Wii U edition.
Minecraft: Java Edition is basically its own Minecraft entirely, and dropping support for that version would be suicidal as it has an established mod and fanbase.
The Bedrock engine is used on platforms going forth, running the same build as iOS, Android, and Windows 10 currently. This comes with benefits, for example skins that are purchased through the appropriate store platform (like skins on the PS Store) will be linked to your Microsoft account, and that can be used on other devices that you have Minecraft on, like the Xbox for example.
Edit: I'd like to expand my thoughts on the skin purchases. Skin purchases will be done through the console's storefront, meaning a PS4 player buying a skin for Minecraft will still be giving a cut to Sony. This also means that buying skins from other platforms will yield the same results, and since they'll be linked to the MS account, there won't be an option to purchase it twice. Great for consumers and still great for platform holders because they're still not missing out on any profits from DLC transactions. I can only see pride being an excuse not to accept crossplay, and that in itself is a stupid reason.
Why can people get Microsoft to budge on issues, but trying to get Sony to do anything good is like trying to get a cat unstuck from a tree? Ridiculous.
