There does become a price point where it doesn't make sense to subscribe.
Whoever mentioned $120 a year is close to right with me in the sense that I tend to order 2 PPVs a year (Mania and Rumble). However, seeing as how I get the rest for that same price I might be willing to bump that total to $160 or so (ie in my mind the other 10 are worth another $40). That comes to roughly $13 a month, and realistically $15 a month probably doesn't make that much of a difference to me (comes to $180 a month). And the "nice" thing about a monthly subscription, at least from a businesses perspective, is that people like me won't balk at $2 a month like we might at $25 right up front.
After $15 a month I'm not sure I'd keep it. But for those who did order 6 PPVs a month at an average of even $40 a piece, in theory they'd be happy to pay at least $20 a month, and maybe even more if they factor in the other PPVs like I'm doing.
Removing live PPVs, and it's not even close. I imagine there's many more people who care about getting PPVs at a huge discount than there are people really psyched about watching old WCW shows. Encouraging the casual fan who rarely spends money on the product to do so more regularly has to be their biggest goal.
I am the opposite, as I couldn't care less about the current PPVs and would love the archives, but yes we must think realistically.
