Will Google ever release Picasa 4.0?

Google hasn't really given Picasa any major update in a while, are they going to release a new version? Its been stuck at version 3.9 for sometime, so are they just trying to move everything to chrome / the net and services like google+ photos or are they still serious about the desktop? It would be a shame, I think it's probably the nicest and most intuitive free photo manager around.
