This makes complete sense, but it's nice to have it confirmed -- according to Shack News Sony has stated that downloadable versions of PS Vita games will be 10% cheaper than their regular box retail counterparts.
Interestingly, possibly as a direct response to issues with the PSP Go, best buy in the US will be selling downloadable codes of games in store, still at the 10% discount. Neogaf user GQman2121 spotted multiple titles sporting the same discount.
It's an interesting compromise, and I'll be interested to see the results. As games move towards digital, particularly with handheld consoles, we're in a massive transition period. This allows Sony to minimise their outlay whilst also providing retailers with something concrete they can sell.
