I loved the original Starcraft because before that came out I was really into the original Age of Empires. The only reason I stopped playing SC when I did was because I was fed up with the amount of cheating there was. No fog hacks is what I specifically remember getting on my nerves, but I know there was more like resource hacks and stuff.
I am sure they will have this stuff in mind for SC2, it being 10+ years in the making and everything, lol.
I cant wait to try it out!
