There will be just as many combat skills as there are magic and stealth skills, and FYI there will be magic and stealth perks as well as combat perks.
Combat has not been relegated to "perks only". This is a totally irrational fear, and just plain delusional considering that we know there will be 18 skills and that each of them will fit into one of three groups of constellations in the sky (the soceror, warrior and thief).
There have been changes to the combat skills (blade and blunt now = one-handed and two-handed, armorer now = smithing, etc.), but they are no less represented than the magic and thief skill sets.
