Already addresed Cortana.
Like I said, 6 minute E3 demo... Way to early to say even that level is "extremely linear". They had to introduce new enemies, new weapons, this could not have been done in 6 minutes outside of a controlled enviroment.
But we obviously have a different view on this, so I'll part this discussion, and I'm sure we'll have a renewed conversation when the game is out and we have the full picture.
