nChain published an announcement of the creation of Bitcoin SV.

Bitcoin-SV (BSV) is the altered version of Bitcoin Cash protocols. BSV is likely to bring a potential fork of Bitcoin Cash by causing incompatibility with Bitcoin Cash network and therefore create a new cryptocurrency asset - Bitcoin-SV (Token: BSV).
 
Should it happen, will Bitcoin Cash holders at TREZOR will then receive BSV assets against a 1:1 ratio on their BCH assets?

And will BSV be a success?
