I believe we possibly have plans for adding support for spriter to VS in the future; possibly (well one of the bone apps)
I grabbed the beta version a while back, while it was on kickstarter...
I wasn't too impressed at the time, but that's because none of the 2D bone animation apps are much use for animation towards & away from the camera... they are more geared towards side-scrolling games.
other than that, they are pretty useful
