What sort of tyres have you got on? That sort of wobble isn't unusual with knobblies, and it can come and go depending on the amount of tread left on the tyre. Changing the pressures a few psi up or down can cure it.
Or it could be any of the other reasons. Pretty easy to check the wheel runout and headstock bearings if you can get the front wheel off the floor.
