It's hard to shed a tear for a cancelled licensed game, but in the case of Pirates of the Caribbean: Armada of the Damned will do so, at least on account of the developers who lose their jobs at Propaganda Games as a result of the decision.
Development on Tron: Evolution is said to continue as before while the cancellation of Pirates of the Caribbean: Armada of the Damned is said to result in pink slips for around 100 employees. The game was meant to be released next year alongside the fourth movie.
