Actually, Sony models have gone down a good $200 off their MSRP about 2 months after release consistently over the last 3 years. So, unlike seph22, I expect the price to drop below $1000 around May (possibly around $950). Because of the economy, I suspect the resellers will price those somewhat agressively.
Also, since the CX series got an update this time, I personally don't expect a model refresh until January 2011. Maybe a CX555 and/or XR555 model with more flash/HDD space, like they did with the SR5/SR7/SR8, but otherwise no feature changes (though I could be way off here).
