Can I get (something like) an Apple wireless keyboard with numeric keypad?
Agree with Loïc that this question should be rephrased, but if you're looking for a possible solution without being subject to Apple's whims, there are many third-party bluetooth keypads available...


LMP Bluetooth Keypad -- meant to attach to an Apple wireless keyboard, but has mixed reviews
Microsoft Bluetooth Keypad -- blasphemy, I know, but it has good reviews
Logitech Wireless Keypad -- non-Bluetooth alternative that uses Logitech's mini USB receiver
