The one sure thing is that a much-anticipated Apple event will spend the first 15 discussing something we don't really want to hear about.
Look for an extended discussion/sales pitch about the AppleOne bundle.
On the product front, I think the silicon shortage will push the iMac intro to the WWDC in June.
So I'm thinking the iPad Pro gets an update, and the main event is the new AppleTV.
Now a really good games console, with an available game controller and a remote that won't be openly mocked.
