@Meganyan20 Overwatch isn't dead. Yet. I'm almost certain that the 2021 sets were delayed because Overwatch 2 is set to (or was set to) come out soon, and the sets would correspond to that
@Meganyan20 "One possibility is that LEGO is holding back the remaining sets to coincide with the launch of Overwatch 2 whose release date has yet to be announced."
"However, I want to note that Overwatch 2 was to be released this year but was delayed and those placeholder sets could have been tied to the sequel. Whatever the case is, LEGO won’t speak on such matters so we don’t exactly know what is going on at this point but fingers crossed that we get more sets down the line."
