Yep, that should get the customers running. Sony Japan's rather neat free screen protector offer for some Japanese PS Vita games, MGS HD and Persona, will also come with a free bag, if they buy a PS Vita at the same time... I'll repeat that, a free bag! See all the designs at Andriasang.
Now, I like free stuff as much as the next person, but is this going to convince me to buy a PS Vita? Well, I guess every sale will help, but really Sony - a little more imagination and more useful free stuff (memory cards, games) is probably needed here.
