HKEPC (in Chinese) has reported that Via was working on a dual-core version of its ultra-low power Nano processor. According to them, the new chip would be released in the second half of 2009. If you missed it, the Via Nano competes with Intel's Atom in the low-power category and could be used to build Netbooks or Set Top Boxes. The new Nano would use a 1333Mhz memory bus and have more embedded cache memory (128KB L1 + 1MB L2) to reduce latency.
At the moment, this is a rumor, but it is most likely true. Via and other CPU makers have nowhere to go, except continue to improve frequency slightly and add more cores. All of the above sounds very plausible.
