If I were to receive a Beta key is there a downloadable version of the beta for mac on blizzard.com? (at this time)
Not at the moment. It is supposed be available some time this next week, which probably means the week after.
So does "this next week" mean the current week, because I know that was talked about last week. Or will it come next week? -thanks!
It'll come soon enough. I would worry about getting a beta key first. As for some people that's not easy at all.
Just pre-order from Amazon or Gamestop. Seriously buy some cheap used game with the collector's edition and you will be playing SC2 collectors for 75$. Thats what I did at least.
