As with everything worthwhile, the upcoming Star Wars: The Old Republic has a price. What that price will be, though, will depend largely on what's considered "the norm" when it's ready for release.
"The way we look at these things is, 'What's the standard at the time?' Obviously we're not quite done yet. We've got a lot of work left to do. But we'll be very conscious of how the market looks," BioWare co-founder Greg Zeschuk told Videogaming247 at GDC.

So if they mean "standard," you can probably expect to pay around what the World of WarCraft is charging. Seem like a fair price to pay for you?
