On June 13th of this year I saw about a level of Splinter Cell: Conviction with my brother-in-law
A little more gritty then I would have liked - I enjoy my Splinter Cell quiet and in the shadows - this was more in your face.
I've been out of the series for a while (my last game was Splinter Cell: Chaos Theory), so Sam may have been moving in this direction while I've been away.
Regardless, the sequence I saw was still great and something I may be the one at the controls.
