Initially I had thought Heller was going to come out today (Monday). Probably Wednesday or Thursday. Keep your fingers crossed for three things. 1) Individual right. 2) Fundamental right, and 3) strict scrutiny.
Scalia is certainly taking his time writing up the majority position. Rumor has it, Scalia is actually a 'gun guy' so its being left up to him, and he's taking a bit longer to get it right. The court probably has to agree on/create a set of guidelines, or general rules.
Wish I could swing a DC trip just to listen to the decision being read on the court steps.
