How about 'irrelevant'?
It would have happened sooner or later. Sooner, as we've seen from the limited polls and anecdotal evidence, is more likely to generate sales than anything else. In fact, every reputable study of downloading shows little to no negative impact on sales. The RIAA and MPAA disagrees, but they are wrong and backwards.
The people who are ranting about 'DIRTY, DIRTY THIEVESES!' don't really have anything other than an emotional response to stand on. Legally, the most they could get the leaker on is breach of contract, and that's iffy if he\she\they never signed an NDA. Lawsuits are expensive, and when the net result is a sales bump on people who wouldn't have bought it before gaining interest, it's a sign of a company in the process of self destruction.
Get over it.
It's not a big deal.
