I'm assuming Batwolf is one of the 5 you're thinking of. As I understand it, the Batwolf is being discontinued.
You're correct though. I believe the Gascan (for example) is not on the chopping block. The only thing I know for certain is that all models going forward will feature the Ellipse Icon exclusively. It's all about simple brand recognition for them (profits), not originality. Shame.
Fuel cell, Gas Can, Det Cord, Five Squared, Jupiter Squared, and the iconic Holbrook. Just off the top of my head. Gonna be a lot of p'od people out there.
