Core i5 and Core i3 details sound plausible.
We have a pretty decent, if rough, picture of what sort of CPUs Intel will be releasing next year. Intel keeps us in the loop architecturally, but often we're left speculating on specifics – at least until we get an updated roadmap in our hands.
Japanese site PC Watch has details on a roadmap leak that details low-powered "S" versions of the Core i5 750 and i7 860, which feature a thermal design power of 82W rather than the usual 95W. These chips will supposedly run all four cores at 2.4GHz for the i5 and 2.53GHz for the i7.
Roadmap also shows a dual-core Clarkdale-based Core i5 with Hyperthreading that'll launch at the faster clock speeds starting at 3.43GHz and ramping all the way to 3.73GHz.
The Core i3 will also supposedly be splashing onto the market with the i3 530 and 540, with the former running at 2.93GHz and the latter at 3.06GHz. Both will have Hyperthreading to create four logical cores, but it'll be doing so without the Turbo Boost features of the rest of the Westmere family.
Interestingly enough, the Pentium name will live on once again, which will be based off Clarkdale with dual cores without Hyperthreading and Turbo Boost. It'll also have less L3 cache at 3MB.
