microsoft seems to think they can take their time though, and doesnt have it scheduled till the end of the year.
they are going to lose a lot of people to dropbox/googledrive/box by the end of the year, because groove.exe is so terrible.
the OneDrive "Consumer" client was/is based on the orginal Live Mesh product that MS bought
Last year MS announced they were merging the Code Base and Having OneDrive for business operate on the better OneDrive for Business Client, this is the Code name "Next Generation" Client for OneDrive for Business.

Dropbox clients is still better than both of MS offerings however.
You got that backwards. Mesh is the good client, groove is the bad one. The next gen one is the consumer client getting sharepoint support.
Currently, right now, mesh can sync OneDrive for Business but not OneDrive Groups.
For everything else now, you use OneDrive instead.
