PS3 500gb~ £180 (if it happens)
Xbox 360 4gb~ Maybe small price cut to £130
Xbox 360 250gb~ £180
Wii~ Maybe a pricecut to £99
3DS XL~ £150
Normal 3DS will be discontinued altogether
PS vita~ £150 (currently £180 to £200 for PS vita bundles), 3G vita will be discontinued
PSP and DS pricecuts to £79, if at all
