Noticed this as I was browsing the Argos website.
It looks to be a pricing error as the PS3 version is the most expensive of the lot, however if it holds up then either copy is going for nearly half of what it's being sold for elsewhere.
Update: Checked again today to see that the prices have changed to what I assume Argos would have set them at originally. PS4 version is now £34.99, Vita is now £27.99 (ouch).
On the plus side, the PS3 version got lowered to £23.99 which is the lowest I've seen that going for.
