I believe I saw on Tom's hardware that the Palomino won't be out at 1.5 ghz--ah here we are:
"The Register is reporting that a recently leaked roadmap for Advanced Micro Devices is not actually that recent. A presentation by AMD president and COO, Hector Ruiz, to the Morgan Stanley Dean Witter Semiconductor and Systems Conference suggests that Palomino, the Athlon design that will succeed the current Thunderbird, will ship this quarter at speeds of over 1.2GHz, and not in July at 1.4GHz as previously reported."
