OXCGN:
"Believe it or not, Virtua Tennis 4 is not actually the fourth Virtua Tennis game. It is actually the fifth and follows the last one which was released in 2009.
"The game is broken down into a few areas, the World Tour, Arcade and Exhibition modes and if you feel like a bit of fun, you can play the Mini-Games – some of which are very strange.
"Unfortunately, it doesn’t hold its appeal for very long after that though, so replayability is somewhat limited."
Tennis ftw
It does seem to cover a lot, but not tailor itself to one specific genre enough.
I believe the online aspect is decent enough, but these sorts of sport titles only have a specific following, and obviously only have a limited sales market - sadly.

actually, have you guys noticed that both games are at their fourth numbered title
Major coincidence?
