Nothing has formally been announced, but if listings by various arms of Amazon are any indication then a Grand Theft Auto 5 PS4 bundle is on the way.
Three European Amazon sites (Spain, Italy and Germany) have each listed bundles for 449,00 EUR. In comparison, a PS4 retails in the region for 399,99 EUR, offering a 26,99 EUR discount when you factor in the 71,00 MSRP of a game.
Given that Sony and Rockstar teamed up for a GTA 5 PS3 bundle, it's definitely possible we could see the same for the PlayStation 4. Again, though, nothing has been announced yet, so as always take these type of rumors with a grain of salt.
