I'm thinking the Nerf Pro Primary Flywheel (4) is a Stryfe X variant without the lipo. Still a short dart blaster but in a different shell & under a different name. Hasbro would be smart if they included a similar setup to as the DZ Mark 3 to accept the Stryfe X battery and then sell the battery separately. They are leaving so much money on the table not selling those things individually. Can you imagine if all the battery operated Nerf Pro line blasters had this connection point but also had a removable AA tray? I think you're on the right track if a blaster that offered more features than the Stryfe X and came in at a lower price it would really cannibalize the line. I would like to see them expand the nerf ball/pro line and almost take on a player role type of blaster line. This kinda goes against my above idea of them releasing "another stryfe" back to back, but if they have to reset the pro line pricing structure I guess now is better then later.
That's kind a what I'm leaning towards as well. The fact that The Styfe X came out first and it set the standard at $120 and now the line is only going down in price. I just hope we get some decent shells.
