I still don't think that we'll see 75' flat ranges, as that's what the similarly sized Nitefinder generally maxes out at, but I think that 60' flat out of the box is probably guaranteed. More importantly, there is copious room for improvement. I wouldn't be surprised if 80' flat is possible with the correct mods.
I am excited to see clip-fed blasters becoming more competitive. I am also interested to see how these new blasters affect the game of HvZ. While I assume that the prime will still be stronger, I feel like it will be manageable enough to not noticeably impact RoF. With cheap, high-powered blasters being widely available, not to mention new, more stable darts, it will be harder than ever to be a zombie.
