I agree with you completely - Tigrex's remixed theme is absolutely amazing. But I've noticed that they made some minor tweaks with Brachydios' theme as well.

The best guess I have as to why they remixed Tigrex is because he's a pretty popular monster and he plays a pretty important role in the game (stealing the spotlight in the first MH4 trailer and having roles in all the subsequent trailers). He's been in the spotlight ever since MH4 was announced - the others, not so much.

But I could have gone with a Yian Garuga remix too. And Fatalis is in desperate need for a remix as well.
