New XC MTB for 2020 - What to Get?

It does not exist yet. If live valve is as good as initially reported I would love to see a xc light frame and build with live valve, spec’d with 140-150mm travel. On top of that, how about a return to 26” or at least 27.5 wheels. There are so many re-accelerations in xc, worst place to add weight in tires, rims, spoke combo. More plush travel, better traction, lower rotational mass, live valve pedal efficiency, lighter overall bike weight, the holy grail of xc race bikes! Probably a warranty nightmare though for bike companies.
