From what i heard 45nm Phenoms/Shanghais will be very cool chips,even with high volts>The current leakage has been well addressed at 45nm node and power consumption will be a lot lower than at 65nm with comparable clocks and/or volts.AMD also feel confident about their shipping parts so it's wait and see game right now.Not much more to wait,maybe until middle of November or the end of it for Deneb.
