Seibertron.com reports that s250 has revealed another set of spoilers regarding the third season of  the Transformers Animated cartoon. Make of them what you will but, here they are:

"maybe season 3 influenced by Kung-Fu Panda, there are lot of kung-fu elements, such as Prowl having to perform TaiChi to open the door.
Prowl's master named Yokoiron, killed by Lockdown.
Sentinel Prime met Black Arachnia, knocked off her helmet by lance, and was shocked by the face under helmet.
Jazz, Ultra Magnus, Dai Atlas, all ninja tribe
Heavyload, one of ninja tribe's ancestor, just a bust, no show.
Warpath, other ninja tribe ancestor,in prowl's memory, barrel on chest...."

So, more martial arts by Prowl. Good.
Yokoiron. O...K?
Finally! Sentinel finds out about Blackarachnia.
Ultra Magnus is a ninja too? He sure doesn't seem like it. Maybe he's been hiding the fact.
A Heavyload bust. Wonder if it'll be a homage or not.
Warpath's been mentioned before. This is just more proof of his existence.
