ganancias que van a ser mayores

[Nfqufktc]

¡Hola!

Here is the sentence from an exercise book, the answer key has van:

Creemos que la temporada turística este año resultará en ganancias que van a ser mayores con respecto al mismo período del año pasado.

We believe that this year the tourist season will result in / generate / yield earnings that are going to be greater / bigger regarding / with regard to / in relation to the same period of last year.

Would you advise if the present subjunctive may be substituted for present indicative in the adjective clause?

My reasoning is that

• the situation in question refers to the future;
• the antecedent (ganancias) is non-specific (no article) and
• an element of anticipation is present.

Creemos que la temporada turística este año resultará en ganancias que vayan a ser mayores con respecto al mismo período del año pasado.


Thank you.
