The v10 beta I have has it. So you won't have to wait much longer.

  I'm on v10 beta as well, and it still remembers only one undo. Is it v10.0.0.0, or is there a newer release?

    And no redo either, I suppose? Nothing good comes from the current undo function in Mathematica; if you accidentally press it you're bound to lose work.

    I shouldn't have said beta. It's more of an internal nightly. I don't think the version number is different though.
