Wait a minute...does Nintendo do this? I don't remember seeing the same mario vc games on both systems....The problem is that you think Nintendo can remain competitive by remaining separate from their own products, charging you $5 for super Mario bros 1 on Wii, then charging you $5 more for Super Mario Bros 1 on 3DS, you are wrong.
The iOS model of unified purchases across all platforms is clearly a superior choice for the consumer's game purchase.
If you honestly think otherwise, then you are ok with rebuying same content on different platforms from the same company and there's really nothing I can say to change your mind.
Sony really dropped the ball on that too. They could have done something like: Bring your UMD games to a Sony store, turn them in and get those games added to your playstation account. Boom, instant game library for Vita that you already paid for once. Nobody that has a PSP and UMDs wants to rebuy those same games digitally.
Also, I am looking forward to the real GOW sequel being announced at E3 for Vita!!!
