Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Retail Sources Confirm iMac Refresh
As GeekSugar predicted, the prices for U.S. systems appear to be identical to existing iMac configurations ($1199, $1499, $1799).

No stores have seen any evidence of Mac mini product revisions, however, so it appears the iMac is the only system to be updated.
