I think that GMAT Club is a great community but not really representative of the whole CBS applicants population (and overlapping a lot w/h BW), and moreover it is not so unusual not to hear anything in the first month, I mean statistically speaking.
Yet you may be right, we're all speculating, the only thing I knew is that my friends at CBS told me that a couple of guys have already been admitted for J-term but he may be well misinformed or it may even be a particular case.
I don't know, it does not make much sense to me that we're already under review since on RD all the people that applied before Jan 6 got printed and actually under review on jan 6, but again there might be differences between RD, J-term and ED.
To be really honest is not even about getting an early feedback but a positive one, if I get it after aug 16 it will simply mean I'll have a little longer summer holiday... :D
