New Sony Vaio P Series

The new Mk2 version of the Sony P-Series is about to be released.  I'm selling my white P11Z in anticipation but am wondering which model to replace it with.  I definately want black this time (see pic) but the 2.13GHz model is pretty exepensive and the 1.8GH model doesn't have the US15X chipset....  I think the VPCP11Z9E/B is the only option!
