I will be surprised if they do another game. Or at least it will be open world (which could be interesting)
I really enjoyed Blacklist. I thought the story was somewhat interesting and I didn't have a problem with Ironside being gone. The thing is that it was a mutual decision to have somebody new. He couldn't do the motion capture part of the performance so he stayed on as a narrator and adviser. Considering Ubisoft changed the character of Sam Fisher when it was first released based on Ironside being the voice actor it, I don't think they did out of carelessness.
I also enjoyed the co-op campaign and co-op survival mode. They were ****ing fun. The only thing that ruined the experience was the last mission/boss. It was a quick time event and it was ****ing unforgiving.
Agreed on all points except Ironside. Him being gone wouldn't have been terrible, if they got a suitable replacement. The new Sam was a typical soldier type, grunting at everything and always coming off as pissed off. None of Sams original character, wit, or dark sarcastic humor.
Lambert: I'm hearing gunfire down there, Fisher. Is everything alright?
Sam: It's coming from up ahead, but Lambert... when I think 'guerrilla', I think 'Kalashnikov'.
Lambert: What do you mean?
Sam: I've had enough AK's fired at me in my time to tell you that wasn't one.
The insurgents seem to have advanced weaponry.
