Great news.
I'm looking forward to it, and I'm also happy they do 10 episodes. I really liked the recent "mini-season "(Season 10), but IMO it was a little too short, and might have forced Chris Carter to put too much "trade mark X-Files" stuff into only 6 espisodes, which made some of those feel a little "forced".
Granted, some episodes were a little slow, but "Mulder and Scully Meet the Were-Monster" (Episode 3) was absolutely brilliant.
