This is indeed the Guild logo. It has been around since MH (PS2) and can be found in various places including the flag in the Fortresses opening area (where Shen Gaoren and Lao Shan Lung are fought). Some armors also have the symbol.

MHX just happens to bring attention to the symbol moreso than past games did. Gaijinhunter made a great video explaining the Guild logo's meaning.Check it out if you'd like.
