Shooting Game Historica 2 SP

As the first set of Shooting Game Historica had an SP (second product) edition, so will part 2 of the shooter fan acclaimed gashapon. NCSX sent me an email saying that Shooting Game Historica Vol. 2 SP edition is up for pre-order. As excited as I was back in April that the gashapon shooter series was getting a second set, I knew it wouldn't be long before the SP edition of Vol. 2 was announced. While NCSX doesn't have any information on the extra repainted ships in the set, they do have a much better picture of the final painted models. As a quick refresher, Vol. 2 includes Fantasy Zone's Opa Opa, R-Type III's R-90 Ragnarok, Star Blade's Geo Sword, RayStorm's R-Gray 1, and Star Luster's Gaia. The regular ships were packaged in plastic bubbles, while the SP ships are in fancy tiny boxes. I'm assuming that one of the ships may have two alternate colors as Darius' Silver Hawk came in red, blue, and yellow in the first SP set. There is also no new info on what that secret ship is, but I can read that warning now. It says "WARNING!! Unknown flying object is approaching fast!!" The silhouette looks different than the one on the regular Vol. 2 set. Are there two different secret ships or is it just a different angle? Shooting Game Historica Vol. 2 SP will be out in September.
