Taipan has an instagram page and will occasionally hint at something big coming in 2021. I suspect that forward/mid cocking is at least one of the big changes coming.
Yes, there was the Mutant before the Veteran, but I think the only changes made to the Vet were how the barrel attaches to the breech, and the anti-double load feature. Other than those minor changes, the Mutant/Veteran platform has changed very little. Even when they went to Minelli for the laminate stocks, they kept the same profile/shape of the stock.
Personally, the rear-cocking is not a deal-breaker. I don't even feel like it's a niggle. It doesn't seem or feel awkward or even like a slightly unnatural movement. I've found that it works great to keep the trigger finger/hand on the grip and reach over the top and cock and load (if using single-shot tray) it with my left hand. I considered swapping the lever to the left side since I'm cocking with my left hand but that would put the lever in my cheek, it would also make the gun need to come out from the shoulder more to get enough room for the cocking lever to make its full travel distance. With cocking lever on the right side of the gun and using the left hand to reach over, I can keep the gun shouldered for cocking.
I think the gripe about rear-cocking is sorta like giving the gun a 9.9 instead of a 10, cuz people just gotta find SOMETHING to keep from saying the gun is perfect. Oh, as long as we're LOOKING for something wrong with the Veteran, let's not forget to say that the stock looks blocky or like a 2x6 or etc etc etc.
