bio--
you are correct, the company did not confirm earnings date, yahoo is always just an estimate. I was trying to see when they posted earnings last year, could not find pr.
If they really had to they could just file a 10q and be done with it, no pr or anything
the conference is the only "reliable" thing to look forward to, meaning that they could always delay the report
If they cancel the conference for some reason, I would assume that something is up, if not, and they show up as scheduled, all ears will be listening
