Like I said earlier, the mass disagreement on what price it could be indicates to me that we really can't predict anything, because this is sorta an unknown aspect of FFG's pricing philosophy.
We know Ion damage is considered an upside on a hypothetical 4 dice range 2-1 canon with upside. We also know its considered an upgrade on the HLC. Its a VERY large upgrade on turrets as we know. On torps is a downgrade, which indicates to me that FFG values the ability to get to 4 red dice very highly, and considers 4 ion dice to be not much better than 3, which sorta scans. Overal it seems like being able to 'push past' 3 base damage dice on a range 2 attack is at a premium in FFG's eyes. All of this is evidence that the fact it is 'only' 3 dice will keep the price lower.
Conversely, maybe this is considered 'better' than the HLC because of the wider angle, despite the HLC allowing you to hit 4 dice. It might be intended as a HLC 'sidegrade' because they want long range canons that are pure damage but don't want to lower the HLC's cost more, at which point it might sit at 6. I doubt it would go higher, because there is no way access to the 3rd range bracket is worth more than 3 times as much as autoblasters, but maybe they DON'T want to push long range canons and this is going to avoid 'stepping on the HLCs toes.'
There are strong arguments to be made for a LOT of price points, because its the kinda effect that really doesn't have a great 1:1 corollary in the slot it is in, and stuff in other slots can either range from 'its generally not expensive to get a 3 dice range 2-3 attack' to 'it is VERY expensive to upgrade your long range damage.'
I am personally thinking 'there is no way in **** they are more worried about this being spammed than ion cannons' camp. But 'this is a better HLC' camp is a pretty realistic reality to live in too. We just gotta see what timeline we end up on. What we really might be seeing here is how comfortable FFG is going to be making canons 'about' control effects, vs wanting to make attractive damage canons so that they can make canon synergy tools.
