Godzilla's Sentience

Hello there. I've a simple question: just how sentient is Godzilla going to be within the scope of Edwards' upcoming film? How much intelligence and self-awareness is he going to evidence? As he stands roughly 350ft - give or take ;) - in height, he must surely possess an immesne brain, at least with regards to volume. Not only that, but a creature of such enormity would very likely require considerable cognitive potential in order to move its massive form and remain spatially aware. With this as the case, could we expect Godzilla to show problem-solving skills - or perhaps even the capacity to use simple weaponry, such as using his tail as a flail or lifting a ruined monorail to use as a bludgeon? I know that sounds a bit hurly-burly, but do you suppose it's something we'll see? Other manifestations of Godzilla have done these things in the past; does it stand to reason that we mightg see this in Edwards' upcoming revamp? Oh, and for those of you who've seen Godzilla vs. King Kong: there's NO WAY Godzilla's brain is the size of a walnut. NO BLOODY WAY! This girl calls complete and utter balderdash on that rubbish! ;) As always, you're thoughts and conjecture on this topic are most appreciated, even if you choose to keep them to yourself. :)
