Freescale should integrate the Ethernet PHY inside the chip
If Freescale can integrate the Ethernet PHY inside, it will be best seller. An external PHY is not cheap.
What? Almost every MCU
What? Almost every MCU company has MCUs with integrated PHYs by now. And external PHYs are cheap. The magnetics cost just as much, if not more, than the PHYs in many cases.

MCF5223x has integrated PHY
Freescale does offer one chip with the integrated PHY, see the MCF5223x:

It's slightly more expensive, offers more integration.
It's an interesting discussion about integrating PHYs etc. I've heard some people say it can limit the flexibility in the design, i.e. if they want POE and the PHY integrated doesn't have it. Also others might want IEEE15888 vs. POE. I suppose it depends on what is critical for a design.
RE: MCF5223x has integrated PHY
The truth is that Freescale is indeed one of the major players in the microcontroller market, but as far as the "low power" feature is concerned they are not near the top of the range. TI is the best there, followed by both Microchip and Atmel neck to neck one could argue. But then again, Freescale has other advantages in its portfolio and it looks like being the preferred automotive supplier compared against all the other three mentioned above.
