If you think about it, GTA5 is going to get millions of people in stores within days. These are people that most likely wouldn't have been in the stores if it wern't for GTA5. Now that there are millions more people in the videogame department they will see Sony games and want to buy Vita's, Killzone, etc...
In conclusion, big blockbusters help not only the console it's for but the whole video game industry :)))
For instance let's say 1 out of ever 1,000 GTA5 buyers would be interested in Killzone Vita but didnt know Killzone Vita existed
that means Vita/Killzone sales could have been boosted by 1,800 in GTA5's first two days. Now do this with more games..of course it would help ps360 a lot more but you get what I'm saying. Same applies to wii.
