RE:Why this lull of news? I have a theory on that absence of news. This is just my personal opinion, though, and nothing more.
They painted themselves into a corner with that HC deal. Something tells me that this deal looks like this: ''You give us Colonsentry for free up until Aristotle is ready and when it is, we will pay the FDA approval fees and maybe get an exclusivity period on that new and shiny test.'' Or something similar. And, of course, everything must remain secret.
If it's something like that, the only news we're gonna get in a while is Oncore stuff and, eventually, some Coastal updates. Oncore are late in their previously announced timeframe so who knows when we'll hear from them. The longer they take to setup their network, the more money SZLS will have to pluck from that last pp to sustain their effort (let's not forget that part of that money was to start Oncore up). As for Coastal, one can only guess...
If my theory is right, then we will all be very happy down the road but... way further down the road. Nowhere near the present day.
Again, this is just personal opinion. I'm trying to imagine possible scenarios for this silence and this is the only one that makes sense right now. Anybody, feel free to destroy that theory so I can feel a little bit less frustrated right now.
