Yeah, I found weird that they used Ghirahim's boss theme in the Treehouse announcement video. I am try to not read too much into it, though.Ah, I see. That would be pretty cool if they were dropping hints there. I thought the biggest hint was that Ghirahim's music was used so thoroughly in the Mechareggie Treehouse video. Tell me no one wants a Ghirahim stage with matching music that takes place in the spiral down place where you fight like 5 bosses. Boss of that stage would be the big black thingamajig, it's all so perfect! I'm going to be so pumped if/when he's revealed, we should throw a party *playsKazoo*.
Your idea for a stage sounds cool, but we already have a Skyward Sword stage in SSB4...
