maybe. though for an expensive tv im sure i speak for a lot of people. id feel more comfortable with screws in studs stead of drywall
we hang phone systems that cost in the range of $1000-$3000 with these anchors, the good ones (IE, the auger type or the butterfly type) will hold 50+ pounds each and are harder to pull out of drywall than it is to pull a drywall screw out of a 2x4
these things are no joke\
and yes, we have used them on VERY old drywall/sheetrock (the crumbly kind) and they still work just fine
