Actually, no matter what Graham says, it looks like a prototype design picture...it could be a real pic, but to me it looks like a really good design photo with realistic shading and whatnot.
The (bad) pic of the Nerve looks like a finished version of the 03 Shocker...if you look at everything, the Nerve looks like the 03 Shocker with an air chamber up front.
As far as the extra nib on the bottom of the regulator, it's the blow-off valve. If you used to own an old-style Shocker it was that stupid brass piece that you had to wrap your fingers around if you mounted your reg vertically.
SP has always maintained that you only need their tank regulator, so they like to use a Gas-Through Foregrip, and it looks like they did what WDP finally did with their Angels...if you remember the old LED Angels they had a little tube going from the regulator ASA to the gun body, via the grip frame.
To me, the only way they can keep calling their main marker a "Shocker" is if it has two solenoids, a poppet valve, and a ram. They'll have to do some pretty fancy arranging if they can keep all that AND improve the Shocker's gas-hog reputation.

SP has always been a little behind the times with their Shocker design, and it's nice to see that they've gotten rid of the "clunkyness" of their regulator...I really liked my old Shocker, but the interior was a mess of wires 'cause SP was like Budd Orr with the "Straight from the factory, Stock, is good enough for everyone" attitude and I added little things that should've come standard (like a blinking LED and an On/Off switch...the blinking LED was easier to tell if it was on or not in bright sunlight)...one of my old teammates was reminiscing that I was always good for at least one or two eliminations a game with that gun...I actually liked tall guns, but the fact that I could only shoot five pods made me switch...first to an Angel (Cobra modified, but I can't shoot an Angel)...then to an Intimidator, mostly because it feels like my backup 'Cocker and was super reliable for me (and I had access to all the mods), and now to a GZ...the fire rate of the GZ is awesome and so is the reliability and the fact that if you have the right barrel (I really only need 2 barrels, a 0.694" and a 0.700" but lately I've been using a 0.689" for supersmall paint), it'll shoot any kind of paint but I still miss the accuracy of my Shocker. I occasionally break out my backup gun, my STO, just so I remember what it's like to hit someone on the little toe on the first three shots, but the way that I play now (I'm the guy who's supposed to give the other team a heart attack) I have to have an E-gun, especially if it rains...oh well, times they are-a-changing.
