FUJI F300EXR, OR F500/550EXR??

Just in these days at the CES Fuji has introduced a step-up model of the F300EXR, actually a pair of models, F500EXR and F550EXR.

Both have a new CMOS 16.0 MPixel EXR sensor and FullHD; the 550 model will have also integrated GPS, and RAW capability.
They will be available in March, so do I need to wait??
