From IGN's coverage on it (found here) It looks like Activision/Blizzard is going with the $60 MSRP on it... I know it's just ten bucks - but it's enough to make me hold off (at least until target or best buy have it on sale)
I think the last RTS game I played was Red Alert 2. I'm sure this will be a big seller, but the only upcoming Blizzard game I see myself possibly delving into is Diablo 3..
Starcraft is one of the games I keep playing. Not online, but the original missions. I just play a few of them, they are still fun. I often try to see how fast I can win them.
