Hereafter are details about stocks of iMac and availability for new purchase:
- reference MB950, iMac 21.5" Radeon HD @ 3.06 GHz: not available for new order (EOL)
- reference MC413, iMac 21.5" 9400M @ 3.06 GHz: not available for new order (EOL)
- reference MB952, iMac 27" based on Core 2 duo: not available for new order (EOL)
- reference MB953, iMac 27" Core i5 @ 2.66 GHz: : still available
So, we can expect that Apple will entirely refresh its iMac models, by eliminating all Core 2 Duo-based models, and potentially move to Core iX only CPU. The only model available for re-order might become the new entry level model, while the high-end should offer faster GPU and Core i7 CPU.
