I don't get the impression that WP will replace php templating. That just doesn't make any sense to do. First the code is already written (no need to rewrite), probably well tested, php is extremely fast already, and I'd imagine their php development does not have dated tooling that makes development painful. There's little to no reason to switch php code out.

However, it does make sense to replace JQuery snippets or custom in house dated JS frameworks, especially if they lack modern tooling surrounding it like pipelines, code splitting, etc. In that sense, vue and vue's paradigm is a perfect fit because of it's ability to play well with the primary goals at any level of JS-ification, from simple JS actions to full SPA.
