For me? The delay to March 9th sucked the worst.
Given, the February 10th delay was longer, but I understood that Sakurai needed more time to do a good job completing the game, and February 10th was still in time for my Spring break in March. Plus, Sakurai gave us Sonic to try and make up for it.
But then here we are, less than a month away from our release, and BAM, another month added on. No special updates, we KNEW development was just about done, Sakurai gave us nothing. We would've been spoiled either way.
So yeah, March 9th sucked, big time.
