Bottom line, they wouldn't eliminate something that was working for them. For all the people whining oh my God they're going to be sorry, missing all MY business.. No. No, they're clearly not.
not acknowledging that selling to more people at lower prices creates more profit than selling to less people at higher prices is just poor business sense
Except we've already seen this sort of pendulum swing, in the indie market. Devs found that the "mass sale" strategy on Steam, PSN etc. was not working, at all. Tons of games readily available at $3 made them nowhere near enough money in sales while also encouraging people like US (haha) to just wait until any damn title was available for $3. It doesn't work, and in the AAA physical segment, where it is already widely known that budgets are only ballooning further and further out of control, I highly doubt the pattern would be any different.
Besides - we're not talking about the actual pubs here, we're talking about BB as the middleman. They have to deal with the wholesale prices paid to the pubs and their (profit) numbers are not going to have the direct link to sale prices you're presupposing. I agree with an earlier response: they are most likely trying to reduce their footprint in the video game business entirely.
