When you see a CR1 rumor, its just there as a discussion item, and very unlikely to actually happen. Just think of it that way. CR2 might have a 30-50% chance. CR3 is 95%.
Of course, buried in those hundreds of CR1 items there are bound to be some that are correct. however, no one knows which.
There are lots of topics about photography in general, and opportunities to learn and to teach. Take advantage of those.
