Lil Wayne Disses Jay Z on The Carter IV album on "Im Good" ft. Jadakiss & Drake

Is this good for rap/hip-hop? What is your perception of this?
On the record H.A.M. off the Watch The Throne album, Jay Z raps:

"Niggaz fantasize about the shit that I do daily,
Like these rappers rap about all the shit that I do really,
Im like really, half a billi, nigga really you got baby money,
Keep it real with niggaz, niggaz aint got my lady money."

Do you think that was a shot thrown? Does this stem back to 2009 comments by Birdman?

LISTEN HERE: To LIL WAYNE'S response on his new record off The Carter IV album. Some say it was wrong on Lil Wayne's part, because Jadakiss features on the record first verse, and is signed to Jay Z. What will this cause?
