There are several low-cost (PIC32 range) ARM Cortex-M3/4 MCUs that have High-Speed USB (I know of at least three including one I have in hand , <$4 in quantity) already on the market.

Would you care to supply details?

If you really want to know, please take it offline and send me a PM.  Don't want the crybabies to start screaming about promoting competitors' products.

The Phy tends to be complicated.

HS USB PHY is not so complicated, but integration of PHY makes silicon process complicated. Using external PHY, like Ethernet, just SIE is integrated in the MCU.
ULPI (UTMI+ Low Pin Interface) is a common HS PHY interface. It's a 60MHz 8bit-parallel bus.
ST announced integrated HS PHY on STM32F20x first, but after all, ST has released the MCU with an external ULPI PHY. If Microchip would release HS USB PIC32, they should take an external PHY, too.
ULPI chips are sold around 1 USD in volume price on the market.

Most of the manufacturers offering HS USB use an external PHY via ULPI.  The only exception that I am aware of is the LPC18XX that has an on-board PHY for USB0 and a ULPI interface for USB1.
