The path of disappointment is well-travelled but not smooth. The five stages following an announcement are familiar to all - anticipation, patience, disillusionment, rage and indifference.
Exodus: Proxima Centauri Finally a replacement for Eclipse but with decent multiplayer? The nearest thing to Twilight Imperium for iOS? Announced March 2017 for a summer 2017 release. Radio silence since August 2017 when a UI demo appeared.
Battleheart 2. Ok, to be fair I’m still hopeful about this one. Originally slated for mid-2017, but it has drifted back to maybe June (ie now) according to TA. Fingers crossed.
Analogue: A Hate Story. Before Inkle’s 80 Days showed what could be done with narrative games on iOS, Analogue was announced in September 2013. Apparently a build of the port was demoed, and Golden Gear Games still show it on their website, but after 5 years...? Yep, at the fifth stage for this one.
Any other favourite announcements for which you had hopes and which subsequently disappeared like so much mist?
