I know that seasons carry across platforms, but I haven't heard anything about the 30th Anniversary being a one time buy or if it's something that I will have to buy on multiple platforms. I know that Witch Queen is platform specific, but I'm not sure if the 30th bundle has been mentioned anywhere, but if it has, I've likely missed it.

The 30th anniversary is a dlc & does not carry across different platforms like seasons do.
