A nice fan drawing, but ultimately it's just that: a fan drawing.
Whatever Godzilla's opponents look like, we don't know anything for certain yet regarding their physical appearances. Wings, multiple legs... That's great and all, but what does it really say? Is the multi-legged MUTO a spider, a centipede, a beetle larvae, a caterpillar? Is the winged MUTO a moth, a bird, a flying squirrel?
The point is that with or without the tiny bits of info we've collected, we don't know anything for certain about them. The creatures used in the Comic Con teasers were meant only to tease what Legendary is going for, not to display the final designs of the creatures themselves. So for those who are trying to say "I FOUND SOMETHING!!", just give it a rest. None of us know what the MUTOs look like yet or what they're capable of or exactly how big they are or how many body parts can split into however many segments.
Just relax and enjoy the information we have. The next trailer will be around sometime within the next month or so, maybe a tad longer, and the movie itself is only about three and a half months away. You can afford to be patient and wait for solid facts to become known before throwing out speculation and claiming it as hard evidence or fact.
