By this time [Q3 2011] the platform should be finalized, and this includes bios and drivers, CPU and motherboard, including all the other collaterals that they have to take in account. With this in mind, it looks that there will be more than a year and a half before Pine Trail-D, Atom 2010 platform gets replaced with Cedar Trail-D. Pine Trail-D will definitely have unusually long product life, but we are sure that Intel can come up with some faster version with some minor refresh at some point in the next year and a half.
