Ok firstly doesnt anyone know when the x230s will actually be available to non-chinese persons???

Back to my main question, the source below says the x230s will weigh 1.28kg:

Lenovo ThinkPad X230s unveiled in China: a thinner and lighter 12-incher

However, the x201s 4 cell (1.1kg) and 6 cell (1.23kg) versions were lighter than this, according to this spec sheet:

which seems a little odd- so does anyone have any additional information?
