Depends on your definition of God. If it includes perfect and omniscient, then that being can't make any decisions. They've already been made for him / her. That god is an automaton.
Or alternatively, s/he has "already" made all decisions outside of time/at the moment time began. From this point of view, any being that is both omniscient and omnipotent cannot change his/her mind, if said being changes over time, this implies s/he will make decisions now based on how s/he will feel about things later, after taking her/his own evolution into account.
I'm sure we're not saying anything that hasn't been said literally millions of times before half-drunk at countless frat parties.

You see, the problem is that people think of the evolution of an omniscient deity as a strict linear progression from cause to effect, but actually it's more like a great big ball of wibbly-wobbly timey-wimey... stuff.
