If you take that upper case N from the word Novel and turn it by 90° you have Z. Now you can look for anagrams that contain the word "Zero", but only if you use the words from A and B. And like Lehow points out theres the same amount of letters in each image. There could be further images C, D, E,... and/or we're not even looking at anagrams.
Without some hints from Aksys, there are just too many possibilities to keep on guessing.
That fact that we have an announcement on Aksys facebook page containing a Zero and a 3, combined with the fact that neither the guy from Aksys nor a mod has stepped in and told us to stop is a good indication that this might be it. The only thing thats kept me sceptical since yesterday is the url 4infinity. It leaves open the (unlikely) possibility of either one or 4 infinity games being localized, but I think it's either a red herring or the Japanese name. Over there, the Infinity series was very popular, ZE wasn't. They could just call it "Extreme Escape Adventure: 4 Inifinity" over there to get a few more sales.
Maybe the second 03 will turn into a 02 tonight and we'll know that "Zero 3 will be announced in 2 days". Let's just wait, I think its looking pretty good that this will be it.
