Warcraft 3 is not an MMORPG at all, instead it's a legitimate RTS (World of Warcraft on the other hand is the mother of all MMORPGs!). DotA as of now is a custom map, for warcraft 3, which is neither an RPG nor an RTS. People prefer to call it an Action RTS, or in the case of HON and LoL (Recent DotA spin-offs) people call the genre MOBA (Multiplayer online battle arena). It originaly started of as a custom map for starcraft and later was ported to the superior warcraft engine where it dramaticaly grew in popularity. Now with the warcraft engine becoming obsolete, Icefrog (the current Dota designer) got an offer from valve to build the game on a different and more powerful game engine (Dota2), which would provide all the functionality of the old warcraft platform while tremendously improving visuals, gameplay, matchmaking and connectivity of Dota. So in short, Icefrog and valve getting together is a very good thing for us dota fans, for obvious reasons!
