Godzilla gets bombed... and survives

Another speculative assumption on my part - but after watching the new trailer, and seeing that ending, it really makes me think that we're seeing Godzilla right after he just took the brunt of a very large bomb. The reason I say this is because as he's turning around, you see building debris fall on his spikes and roll off. This debris was not resting on his spikes and simply rolled off, it was falling from the sky. 

Not to mention, the atmosphere being extremely smokey - leads me to believe that this scene is from when Godzilla survives a bomb attack by the Military, and roars in triumph:
