I'm totally piling on false hope, but two things stand out about today... First, look at the live stats. According to that, half the admits got scholarships! That seems quite high compared to last year's percentages. Although, maybe this is explained by a large number of WL admits (no $$$) later, or just that scholarship people are more eager to update their stats. Who knows!
Second, the calls went quite late today. Maybe adcoms love their jobs so much that they would stay past 6pm until whenever it takes to finish their calls. Or maybe they simply went home with some unfinished business
