Splinter Cell announcement today

Ubi Soft is apparently planning some sort of Splinter Cell announcement today - in just under eight hours' time (assuming the countdown on this page isn't confusing BST with PDT or something like that). We're not sure exactly what they're announcing, but the name Splinter Cell: Shadow Strike appeared on the publisher's half-year financials recently, so perhaps it's that. We'll tell you when we find out.
