I highly doubt that they will do a Walking Dead ahead of AC/DC, LOTR, Tron, and Pirates of the Caribbean. Unlike these other titles, you can still buy a new Walking Dead at the regular price. Also, unlike the other titles I have listed, Walking Dead premium can be found pre-owned for 10-20% less than its original selling price . People are still asking for the new selling prices for the pro version of Walking Dead, however I doubt that anyone would pay that when they could find a new one for that price. I also believe that the horror themed games with very graphic artwork like WD limits the market for those games . If you have small kids or just don't want to look at blood and zombies all of the time, you will not buy WD ..
I would bet that we will see either AC/DC or LOTR as the next VE in the coming months ...
