Okay, I have it and here are my impressions of it so far:
I like the handle, the finger grooves work really well and so does the blade cut-out with jimping.
It opens up really fast, I just barely hit the thumb stud and it flies right open.
The redesigned extra-low profile pocket clip works well and doesn't annoy the base of my hand like the older design does on other SOG knives that have it.
The only thing that I find annoying is the safety lever lock switch. I have to use a fingernail to move it as it abrades my finger tip.
It looks like this uses a cam-action type lock with a button instead of the Arc-Lock.
Because of this it has very little blade play.
