VR-Zone has posted a news story on Intel's Wolfdale and AMD's Antares CPU

Intel plans to counter 65nm AMD "Antares" dual core processor with their 45nm "Wolfdale" dual core processor based on Penryn core architecture in Q3 '07. Wolfdale will contain 6MB of shared L2 cache compared to 512KB dedicated L2 per core (1MB total) and 2MB shared L3 on the Antares. It seems like 45nm Penryn architecture is highly scalable and it will get Intel back into the MHz race next year.
