No, tickets are going on sale to the public this Wednesday. Buyers seem to be waiting for that sale to see if they can get tickets from Celtics box office at face value (which will still be very high, probably >$100 for cheapest balcony seat (cheapesat box office ticket price for the Orlando series was $98, before their fees) rather than spend the high prices on the secondary markets.
I expect people to start buying on Wednesday once they strike out on the public sale, and the prices will probably jump pretty quick as more people buy...
Season ticket holders were offered their seats (and extra seats if they wanted) as playoff strips, which means that that they are assured the same seats to every possible playoff game in Boston. Thats how I already have my tickets...
