The Prez and Novak crew are battling out on RCtech about their equipment not being compatible. Something about the Pro4 4600kv motor not working right with Novak ESC's in the beginning. Novak being sensored only, fixed the issue. But the battle continues.
I would be surprised if they did come out with a 5th system. Remember how long it took them to come out with their 8th scale systems. Now, in sayin that, I do hope they will as more competition is better for the industry and us addicts
