WWDC starts on June 6th and Apple is expected to either release or announce a release date for the next version of Mac OS X. The next version of course being OS X Lion. But one question that a lot of people are asking is how much will OS X Lion cost to upgrade to from Snow Leopard? If you remember, the upgrade from Leopard to Snow Leopard was a mere $29. Will Apple be able to match that $29 price point again with Lion?
