At their highest levels, Wanda's powers make Thanos look like a pussy, yeah. Check out Avengers Disassembled and House of M era to see Wanda become a frickin' goddess who manipulates reality to her own will.
Doubtful that Joss has any intention of pushing her powers that high yet in the MCU, though. I'd look for her instead to be modeled after the witches in Charmed, that sort of thing.
