That's not entirely true. They're both great games, in their own ways. While Warcraft III is more friendly, more can be done, and more precisely/overall betterly (if that's a word) with StarCraft II. They each have advantages and disadvantages. It's like saying Crysis 2 has come, and people will stop using Garry's Mod and go to Crysis 2 because it's newer/better, or that Crysis 2 sucks and people will always stick with Garry's Mod. They're totally different, and both have their own advantages/disadvantages. One does have better graphics, but that doesn't make it any better.
