I was playing multiplayer at E3 and this guy started giving me tips on the game. After one round, I asked if he wanted to play. He said he was just watching since he was the producer of the game and was just watching people's reactions. It was Bryan Walker, and we talked a bit on Metroid Prime and Echoes. I admitted I didn't really like the first game (one he apparently didn't work on according to the credits), but the multiplayer was pretty fun for me. He told me that there'd be more to the multiplayer than shown at E3. More powerups and uses for Samus's abilities (stuff we've already found out by now like scanning = no morph ball for other players).
Then he told me that some of the tips he told me while I was playing multi might not be told to the player directly. Meaning that there wont be a tutorial mode some special moves may not be in the manual so players can discover secret moves on their own.
Told you it wouldn't knock your socks off. But I did tell everyone this at E3 so...
