"It remains to be seen who wins."
Translation:Rămâne să vedem cine câștigă.
A more accurate translation is "Rămâne de văzut cine câștigă".
The problem with "rămâne să vedem [...]" is that in some specific contexts it could have a different meaning, more along the lines of "we still have to do/take care of [...]", i.e. it would imply there's an action plan on our part.
