Typically, opinions come out by late June. I say this because my Courthouse always has a CLE- "Continuing Legal Education Program" during which we get a US Supreme Court Opinion Round Up from Dean Chemerinsky. While reasonable minds can disagree with his personal/published POV, he does a 1.5 hr presentation with no notes other than an outline which sorts the cases by topic and name only.
