I think they will go all new. This was the introductory episode and they wanted to give fans some of that nostalgia going in, so they brought the classic levels back. We know
is returning and it looks like
may be along for the ride as well. (But that's all speculation due to an emblem on a rocket.)
Don't expect the controls/physics to change much. If they lock on episode 2 to 1 they will need consistency. I do expect the uncurling to be gone due to the incredibly heavy demand by fans, but homing attack will stay.
What I'm saying is, if you don't like episode 1, I doubt you'll like episode 2.
