NBA Live 09 also continued to receive updates through the 2010 season, most likely unintentionally because the newly added players don't have proper attributes or bio data. I had a look, and the latest 365 roster I have for NBA Live 09 is from those half-complete updates that continued while NBA Live 10 was being updated, not the proper ones from the 2009 season.
I do actually have a PS3 now. The catch is that it was gifted to me last year so that I could import the college basketball games, and while I did also pick up NBA Live 09 and NBA Live 10 (collector's mentality, you see), the servers and roster updates are obviously long offline at this point, so I'm stuck with the default rosters on PS3.
Yeah that's sad, the latest DNA update that i've found, was the 11-11-09 one on gamefaqs i belive, and Tyrus Thomas is still ice cold from mid in this update
