Step 5 higher's have been removed, someone already posted the link to the new payout structure at step 4.
The OP was probably referring to orignal steps
Multi-Table , which now also only has 4 steps.
The original steps single table version still has 5 steps.

Edit: hmm, I still see a step 5 multi table listed to play, maybe they will just keep these as $1000 buy ins, maybe they will be gone when I wake up.
