EA and Reviews

Now, I don't want to start the conspiracy theorists whispering, but did anyone notice that despite the fact that NBA 2k7 and NBA Live were released on the same (or very near the same) day last week, NBA Live was not reviewed until Monday while 2k7 was reviewed the day it came out. What makes this even more interesting is that (going by the reviews) NBA 2k7 is a much better game (8 range). Why would the major sites refuse to review Live until a week after it had released? Maybe it has something to do with the fact that they were planing to give the games 6s. Is there something there or am I just crazy?
