I just did a quick check in the three companies' investor relations page, and here is the timeline for the release of each fiscal report for the holidays quarter:
Microsoft - Jan. 24
Sony - Jan. 31 17:20 Japanese time (maybe even 15:00 if it's included in the "related materials")
Nintendo - Jan. 24
