Yeah, I'd be disappointed if the game was delayed, now that we have an official date. But I wouldn't be upset, or feel slighted or wronged by R*, like so many people are. It is what it is. And others here have stated, I'd rather have a fully tested and finished game (or as close as is humanly possible), instead of a buggy and incomplete mess.
When all else fails, and you're being overrun, grab a meatshield. Hail HYDRA!
