In fact, you can pre-order that PC version right now at retrocityrampage.com, and get bonuses including a mini soundtrack download, a digital manual and 20% off of Fangamer's Retro City Rampage collection*.
And yes, Provinciano is still making all of these versions pretty much on his own. "Maxime [Trépanier]'s been doing art and the music guys are still doing some polish but I'm still juggling everything else myself," Provinciano told Joystiq. Add publishing to that list of duties as well. "I'm self publishing on PlayStation," Provinciano said. "Sony's fantastic that they allow you to do that."
Once this epic undertaking is finally completed, Provinciano hopes to take on something smaller-scale. "I've got many ideas and definitely want to do more open-world games," he said, "but right after RCR I will take a breather and work on something small and different. Hopefully something that takes maybe eight weeks instead of eight years."
