Why wait? Just build/buy a Windows box now if you need something. If they eventually end up making something you like then you can always come back. No one will hold it against you.
I know you are in no way stating this but it seems so many people have a PC vs Mac mindset but the reality is you can own and enjoy both at the same time. I always have machines that runs the latest version of MacOS, Windows and my favorite Linux distro. All are used for specific task albeit Macs running MacOS are still my favorite. If you are good enough you can have all 3 on the same machine (I have a ThinkPad with 3 separate drives (2 SATA SSDs and 1 mSata) for all three OS's.
