"starcraft,
If you bought an arcade or core, you bought the cheap version. If you bought the cheap version, you are not a hardcore gamer. If you are not a hardcore gamer, you don't have a PS3. If you have a core/arcade and not a PS3, you are not wondering which version to get. You know its 360"
==> sure,
but it means that people will not go buy an Xbox360 arcade+GTA4 (if they know what they buy ofc).
The future owners choice will be :
Elite/Premium
or
PS3
then, without price drop, the PS3 is able to match the Xbox360 offer in term of price (400 vs 350/450)
Ofc, there is also the case of people that will just want to buy GTA4 and dont care of the DLC or extra episode, then the Xbox360 arcade is still the cheaper choice
Time to Work !
