Is there newer version of NIS for Mac

Norton 360 for Mac
1

i use NIS4 for Mac for 2 years.My question is related to the release of Mac OS X 10.7 Lion which we can expect in few months.

Is NIS for Mac will be available for Lion or we have to wait months (as had occur with Snow Leopard!!!) until Symantec reacts?

Also is there new version on which Symantec is working or not.There are many obvious improvements that could me made.

 

Thanks in advance
