SWSF as per roadmap ie 95% signalling, which I believe is possible with the AND clause…

The hash power % for the 2MB HF may need to be higher or lower? so to be determined but certainly has to be a large majority.

Maybe 1 year is too soon for dev/testing etc? but should not be too much longer.

The HF can of course have other new features/advances bundled in; not only a 2MB blocksize increase.

Fire away ….
