I listened to a recent interview with him (I think it was this one) and it sounds like he might be doing some Survivorman specials as opposed to a new season. He said the problem with doing a show was they'd want 13 a year and that doing 13, 7 day survival outings a year was just too much for him.

That said, it sounds like he has a lot on the go so I won't be surprised if Izzy is correct in saying we'll see a lot from him in the next while.

In that interview he also mentioned he is in the final stages of development of a survival gear line with an as of yet unnamed company. I believe he mentioned something like 5 knives including a machete & an axe (I think) and some survival kits.
