Did Chuck die? It hasn’t been confirmed - and actually hinted at that he may have survived. To answer your question, I believe it will be back -probably later this year.
I watched Seasons 1 and 2 over the course of a week or so last year. It was great. But OTOH I knew that Season 3 wouldn't be released until a year from then and then it would be released all at once and by that time I'd have forgotten Seasons 1 and 2 and I'd have to re-watch before watching Season 3.
And then someday when they released Season 4 I'd have forgotten it again and I'd have to watch Seasons 1, 2 and 3 before watching Season 4. Etc.
I'm tempted to just wait until the series is over and then watch it all at once.
I'm about to start watching Season 3 so I don't know what happens. But I was fooling around googling members of the cast and lo and behold it seems that the guy that plays Howard Hamlin went to PSU. Someone probably mentioned that on here at some point in the past but since it's new to me I thought I'd say it.
