Now we wait for the submission count....
Update: And here they are. 437 papers, 22+1 committee members, average load of nearly 60 per person. Having done this last year, all I can say is, 'bwa ha ha'.
p.s. There were 392 longs last year, and a total of 487 papers. so depending on how you look at it, submissions either rose or dropped. If you look at just long papers, then the pattern is 224,283,331,360,392 for the last 5 years (averaging 42 per year), and this year the increment was 45.
What remains to be seen is whether any erstwhile short papers were submitted as longs, given that
...authors should feel free to submit abstracts that are significantly shorter than 10 pages.
