Chipzilla Intel is still working another Core i5 dual-core processor. The new model tagged as the Core i5-680 will have a core speed of 3.6GHz.
Despite the higher clocks the TDP will remain at 73W. Being a Clarkdale processor the processor will come with an IGP (integrated graphics core) at a frequency of 733MHz. The CPU will support dual channel DDR3 1333. Pricing wise it is going to be expensive though. Reports claim a 240 Euro price tag (nearly 300 USD). Personally I'd rather purchase a quad-core Core i7 930 or Core i5 750 for that money, but that's just silly old me of course.
