The only year that PC miss NBA Live is 2002 and the reason I think it happened because EA sees the console market being more profitable in 2001 and so they decided to program for the console first. It then turns out that they don't have time to make the PC version so they didn't bother doing it. Besides, in 2001, the graphics card on the PC is on par or even worse than the one in the console (PS2, Xbox vs Radeon 8500, Geforce 4 Ti) so it would make sense to do graphics on the console first...
But nowaday, the graphics card for the pc are way better than Xbox and PS2 and so I think they will make it for the PC...
But, we never know until the end... Like Live 2002 was announce not to be on PC one month prior to the release...
