But if you choose to use Куда мы?
, you should remember it's more colloquial:
Mother: Куда вы?
Children: В парк.
=
Mother: Куда вы идёте? (at the moment of speaking or in the nearest future)
Children: В парк.
Куда вы пойдёте?
can only mean future. Use идёте
or just куда вы?
if you need to refer to the moment of speaking.
IMO, those versions are used in different situations.
"Куда мы?" A typical context: a small group of people walks down the street but unexpectedly for the speaker everyone else changes their direction and that's when the question is asked. Its sense: 'where are we heading to now?' The question is incomplete since the verb идём (going/heading to) is omitted.
"Куда мы пойдем? (Where shall we go?) That's simply about plans for the nearest future.
