I just watched the MP:3 videos, and saw something crazy...seems like this game is much deeper than I had thought.
NOTE: This is a PREDICTION based on the videos, that if true, is a kinda-spoiler
Spoiler Alert!The "Auora" super computers resemble Mother Brain from the original Metroid games. Also, if you wach the end section of this video, you'll see the mother brain in the end scene from both the original and Super Metorid.
I was very surprised to not see this posted yet. If it has, my apologies, and please delete this.
This is pretty big for Metroid fans, really connects the Prime series to the original storyline in a BIG way. VERY cool!
