I don't think that's the case. I mean, it's possible. But the armor's powers and capabilities don't really seem so great.

Since the beginning of the series, we've known that Erza owns well over a hundred different armors. However, we've only been shown a few. So the armor she showed today could've been old to her, but "new" to us if that makes sense.
