3+ years? Star Wars Republic Commando was released in 2005 and it still has server support. They haven't released another game yet so why shut them down?
A shame for those still playing and doing stuff with NBA Live 10, but with the subsequent cancellations it did have a longer run of online support than usual. Hopefully they'll continue to support NBA Jam: On Fire Edition for a while yet.
An NBA Live 14 hasn't been officially announced/confirmed, but I do wonder if the move is at least in part being made in anticipation of a new release later this year.
