With Visual Studio 15.9, Microsoft now supports ARM64 processor architecture as target for Windows software. So Windows now runs currently on 4 architectures: x86 for Intel 32-bit, x64 for Intel 64-bit, ARM in 32-bit and 64-bit. In history Windows NT also run on IA-64, MIPS, Alpha, PowerPC, PC-98 before, so they keep it quite cross platform viable.
Now the big question is whether Xojo Inc. and/or FileMaker Inc. will support the new architecture anytime soon. But if they would, we would of course try to build the plugins for the new platform.
