The problem and the thing that nobody realizes is that SNKP is really screwed with money, to the point that they can't even had money to put their blogs and videos on their own servers
KOF XII development was a living hell for them, if I'm not wrong, the guys made the game, don't like it, and re did it again, I will not be surprised if they released XII because they realized that they got short on money and needed to gain money by any means necessary. Hell, they ended with doubts with their arcade publisher, so they had to go to Konami who was the publisher of XIII
All this emulator games, the lolis games, and all the others games that we had saw were almost all going to finance XII and this one ended giving the money to XIII
This was also the reason of why they cancelled all the Maximum Impact games and a RPG for the DS that never passed trough the first trailer
So at this pont, all this old games in the end of the day are the ones that will finance XIII, but in the other hand, I understand people who don't want to buy this all games, I will do it more for collection value instead of want to play with them (even though, I love psycho Soldier lol) but at the same time, don't ask for them to do lots of shit that they simple can't pull, if they want to focus on pachinkos who gave them more money, I will not blame them, in the end of the day, they are a company, not an ONG
So yeah, is still hard to know if they will release XIII or not, at this point, we don't know much about it, I still hope to see it
