The POS (point of sale) depends on device. Counsols have to use their in game connections to frontier, which will basically convert their devices monitary units to frontiers monitary units and allow the transfer of product. PC's will continue to go directly to frontier as they have always done. Which means that either of the three formats for aquiring products can offer deals that are conducive to their own customers if and when they choose to do so, with out the permission of frontier. Ebox can have a promotion offering what ever while the ps4 doesn't and or vice versa. Frontier can have sales that are not conducive to either the xbox or sony. Where as frontier prices are subject to exchange rates depending on the economy, Xbox and sony can set what ever exchange rates they deem fitting.
