I hope we got some concrete info on the Lost Season soon.
 

Seriously, I will still watch TMNT this Fall (regardless of the fact I think this new storyline with the "Real" Shredder is 100 times more intriguing than Fast Forward) but what I really can't wait for is the Lost Season on DVD. Dan Berger said that they'll get it out on DVD by the year's end. However, in light of what we learned from Good Genes, I think we need some actual concrete info on the Lost Season NOW. That's what I want and that's what I'm excited about. Someone please e-mail Dan and see what he can spell out. Oh and mention Good Genes Part II's revelation. We are all waiting for some juicy new details. :D

Are we even sure the lost season has something to do with the real Shredder? Maybe the current storyline will continue in season 6, after Fast Forward.

Yeah, it could have something to do with a hatch....:P

So season 4 is season 5. The lost season is 4 right. I say keep going don't go back. I mean what is the point.

No. We're currently watching season 4. The "lost episodes" are what would have been season 5 (next season), but they scrapped it and made Fast Forward instead. It would not cover events before this season; it would continue events after this season.

I will consider "season 5" and "Fast Forward" as separate seasons, as FF reportedly will not fit into continuity.

I like the Turtles the way they are. I hope the Fast Forward season is good
If it not goodbye Turtles. I mean it would be cool if it was a five part episode like Turtles in space.
