The claims that there aren't new browsers is wrong as well - there's many of them, it's just that they don't have a marketing team behind them. Uzbl, luakit, surf, jumanji, midori, vimprobable, xombrero, etc.
Well, none of those are new. Breach.cc is relatively new but even that goes back a year. But these highly extensible vim-like microbrowsers you list (excl. midori) have been around for years.
