I think 5.4 is going to really fudge the numbers so they don't seem as extreme as they really are. I expect Q3 numbers to be down about 700,000, or 7 Million subs total left.
I think that real number though, after 5.4 is done for a bunch of people since they've resubbed and are, for all intents and purposes, finished with 5.4 is closer to 6.5 million.
I expect a continued decline through Q4, which doesn't have a new expansion release to prop sales up like past years. In all honesty, I expect the next expansion to launch with around 5.5 million to 6.5 million subs tops.
