I just remembered finishing Black a while ago and it ending with a cliffhanger. If I remember correctly, a sequel was also planned. What happened? Did it get cancelled?
(it's incredible what a 10 second Google search will find)
That article was published in December last year, but they said they planned on releasing it sometime this year. How can they even estimate that they could make a game that fast when they were only rallying developers for it? Also, I find it kind of odd that there have been no development updates from Criterion since then.
Hmm it would be interesting if they did come through with the sequal though. Will probably take them forever to release it though.
