Xbit Labs posted an updated Intel roadmap: xbitlabs.com

Pentium 4 (all CPUs with 0.13micron Northwood core):

Q1’02: no new models to come.
Q2’02: two CPUs for 533MHz Quad Pumped Bus (working at 2.26GHz and 2.4GHz) and one for 400MHz QP (2.4GHz).
Q3’02: 2.53GHz (533MHz QP) and 2.5GHz (400MHz QP).
Q4’02: 2.66GHz and 2.8GHz (both for 533MHz QP) and 2.6GHz (400MHz QP).
Q1’03: "3.x GHz" (no exact frequencies announced).

This is more or less what we have seen in the past. Still, AMD will probably have their hands full trying to keep up.

Celeron.
Q1’02: no new models to come.
Q2’02: Tualatin/256 working at 1.4GHz (the last Tualatin/256), Willamette-128 working at 1.7GHz.
Q3’02: Willamette-128 working at 1.8GHz.
Q4’02: Willamette-128 working at 1.9GHz.
Q1’03. Willamette-128 working at 2.0GHz and the first Celeron based on Northwood core ( L2 cache size hasn’t been announced) working at 2.0GHz.

Hmmm... Willamette 128?

<There is a guy on Aces board who predicts a better branch prediction:>

Copying the Hammer's branch predictor into the Thoroughbred core sounds plausible. It can result in delays though; just like Palomino was delayed partially because the hardware prefetch was copied from Hammer to Palomino very late in the game.

If you believe doriangrey, his friends already have samples of Hammer.
