Since Classic is going to have Millions more players than Retail, shouldn't it be "You pay the Classic subscription, you get Retail for free"?
Instead of the other way around?
Every World of Warcraft Expansion since Cataclysm sees 10 million subscribers at Launch...yes, even Warlords of Draenor.
The Classic Beta was destroying Retail on Twitch, so much so, that - just today - Twitch changed the World of Warcraft logo from "Battle for Nobody cares about this expansion" to the Classic logo with Ragnaros in the background.
Even Google Trends confirms this, if you compare "Classic Wow" to "BFA", Retail is dead, and Classic is on the ascent.
So where does this leave us?
Classic, given the fact it is a game that everyone wants, given that just a level 40 Beta was destroying the current game, given that most World of Warcraft launches attract 10 Million subscribers...I am going to make this prediction now...
Classic will have 10 Millioon subscribers...on day 1.
