Ok, bundles are a good deal. But Sony should still make a price-drop just for the sake of giving customers one more option, especially for people who don't like the particular games that come with the bundle. Also, this could show people that the console got a more attractive price.
I know people who loved the Vita will just get some way to buy it for a cheaper price but most people are not loyal Sony fans, they will just choose between a handheld console themselves and the price gap between the 3DS and the Vita really favours Nintendo's console.
And, btw, the Nintendo 3DS have its own bundles and also got a price cut.
