I'm hoping it's true, but I read one of the latest reviews on PA from someone that said they are making new ones for them. I ended up here looking for more info on it.
I have one in .25 cal, love the gun, hate the magazines as well. I was able to do a semi-fix on mine by loosening the center screw on the magazine so the clear cover spins smoothly. This has worked great for the JSB 25.39 gr but I switched to test the H&N Baracuda's and the Hunter Extreme's and they immediately started jamming up again, I loosened the screw some more and they are cycling again. I can't guarantee that it'll work, but it helped mine, one of the main reasons I bought the gun was because it has a mag for followup shots, without that feature I don't want the gun.
I've got my fingers crossed for new mags being made, I have heard the BullMaster/Barrage/Proxima/Sortie Rotary Mag fits this one, and it's a good mag, they cost $25, in your case I can see getting them, you won it, that's awesome, and congrats, but in my case I shouldn't have to spend another $50 for a couple of working mags, they should have been made right the first time around.
I can say that this is my only real complaint with the gun, I love it, it's light and easy to handle, accurate, powerful, made solid, you can't beat it for the price for a low-cost hunting PCP, others in this price range on the market don't have the power. I can't believe they put out such a nice little gun with the mags that way, it's impossible not to know they were screwed up.
