Rumors of new cameras are generally not correct. That is, something leaks, then the forums get involved, and add a dozen features to the rumor and double the megapixels. Then, when new cameras are actually revealed, the forums are disappointed.
So, let's help out with that process. There are rumors of new Sony DSLR bodies, and a few lenses as well. Most likely, we'll see some version of this come true -- probably Sony will redesign the low end of the line, step up the megapixels, pull out the in-body motors, and add "30" to the model numbers. And release some non-full-frame lenses.
But go check the forums in a few days: they'll say that all the models will have 1080p HD video, and they'll add some magic features that don't make sense at all. Then they'll say there'll be a replacement for the Alpha 900. We'll see.
