I can see a new iMac being announced - that's almost a given.
My concern is with the Mac mini. It's been a great entry level computer for those considering a Mac and I would hate to see that level of product closed out. I would love to see a refreshed mini, plus a mid level for the current mini users that want to move up - but not all the way to a Mac Pro.
Then there is the one more thing and the ultra lite notebook would be perfect. Due to costs it would probably be a MBP level notebook, but from my past experiences with a 3 pound ThinkPad (before I switched years ago) I have no doubts it would be a strong seller, easily replacing the 12" PB.
I wouldn't be surprised to see a new MP released when Leopard is released - buy I'm not sure what intel has in store for Apple in that time frame.
I guess the main question is how much Apple wants to replace at one time. The more products Apple puts out at one time the less media attention each will get. My bet is the iMac and ultra Lite now, with a new mini (and midi?) at Paris and a new MP when Leopard comes out.
As for the iSuites, I would be just as happy with Apple waiting until Leopard is released - especially if Apple comes out with a "You Can Have It All" promotion: Leopard + iLife 08 + iWork 08 (dingle computer or Family Pack) at a special price. Hopefully iWork would finally replace Apple Works in full.
