The sequel for Zone Of The Enders has now been officially cancelled which was announced by Hideo Kojima. It is unknown if the game was taken past concept stages though. SOURCE
I'm frankly very disappointed by this and also I'm not surprise by this. I didn't buy the HD collection because I heard about the framerate issues. Judging the series not to have high enough demand because you made a shoddy port that didn't perform well is really dumb. Of course we want a sequel, and I'll take the HD collection too. But not if it's a poorly-coded, poorly-optimized mess. However I rather have Konami focus on PS4 and latest MSG Ground Zero.
Hmmm, i was on the fence about the ZOE HD collection, if they can fix the framerate issues i will probably pick it up
lol, i rented it just for the MGS2 demo back in the day. It seemed ok but i played the demo too much to remember any of it lol
