Do not forget that the M6 chip will be much better for Artificial Intelligence (AI) and will probably bring PCIe 5.0 (now all Macs have up to PCIe 4.0) with twice as fast SSD inside for both sequential as MB/s and much more importantly random as Input/Output Operations Per Second (IOPS) read/write similar to this Samsung 9100 Pro:
Breakthrough PCIe® 5.0 performance
Push PCIe® 5.0 performance to the max. 9100 PRO achieves lightning-fast sequential read/write speeds up to 14,800/13,400 MB/s, two times faster than 990 PRO. Leave Gen4 limits behind with random read/write speeds up to 2,200K/2,600K IOPS, only possible by Gen5.
Experience exceptional speed with the Samsung 9100 PRO SSD, featuring PCIe 5.0 and sequential read/write speeds up to 14,800/13,400 MB/s.

On the other hand, touch screens are also useful for Macs. Windows has had it for years now. At least Apple should build it into macOS much as is in iOS and iPadOS, at least for third-party displays-monitors that now require third-party kernel extensions with all their problems on Mac. Choices are good.
In this case, the jump is huge. So, yes I will wait for it. This is not a mere update; it is a huge upgrade.
