It's likely that there won't be an HTML6 -- not because HTML5 will be the 
last version, but because we've moved to an unversioned development model 
where there is simply a continually-maintained HTML specification that is 
always current.

It can be that. HTML is backwards-compatible, meaning that an 
implementation of the spec in 2020 will handle content written to the spec 
in 2010 correctly.
