SWSF as per roadmap ie 95{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} signalling, which I believe is possible with the AND clause…

The hash power {88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} 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 ….
