It’s not unusual for servers to shutdown for online games, but it is when it’s so soon. Normally, publishers wait at least 2 years before ending online services. In fact, FIFA 12, released back in 2011, only just recently had it’s servers shutdown, and GT5’s servers will be shutdown in coming weeks after being online for 3 and a half years.
