Steve wasn't one to dwell in the past, so I don't think that a full-blown statue or even a memorial is something that he would approve of and his colleagues know that. If I had to guess, they will consult Laurene Powell Jobs and propose naming the auditorium after him. It is, after all, the kind of place where he shone (and, specifically, where would've shone, had he not lost the battle at all or when he did) the most above all other CEOs (yes, he was also a brilliant CEO behind the scenes, but no one else had such a stage presence and probably never will during our lifetimes), and even more fitting a homage than naming the entire Pixar building (which actually happened) or the entire Apple Campus 2 after him.
That way, whenever a product introduction took place, the invitations and keynote announcements would always bear his name, but the employees themselves wouldn't be dwelling in the past during their daily errands, as Steve advocated and patently stated upon stepping down… Seems like a sensible compromise, if you ask me.
To be entirely fair, the idea for its shape was probably Steve's, but it was designed by Foster and Partners, with input from Jony Ive and a great deal of influence from the previous work done for Apple Stores by Bohlin Cywinsky Jackson…
While you are correct with your ideas of Steve not dwelling on the past ... Tim Cook is the opposite. It's apparent by his constant reminders he speaks about on all the great things Apple has already done. I would guarantee there will be a massive shrine to Steve someplace on this campus and perhaps even an empty office.
