My (opinionated) opinion first....
I don't think Microchip 'unveiled' 20 'new' flash micro's (for full
production in the year 2050) in their press release for nothing. The
'future
products' pdf file on the Microchip site makes for real good reading, if
a
bit too humorous. They can't even fix up a buggy compiler in a year, so
how
would they be able to do a 16C877 (EE version of the '77) in good time?

Now the word-of-mouth stuff...
Pricing seems to be in the USD2 to USD3 range.

Now the verbatim stuff... (It is from the pdf file on the Scenix site)
Introducing the SX series of 8-bit CMOS microcontrollers
from Scenix Semiconductor. The SX incorporates a multitude of
advanced features - each implemented with a practical
understanding of microcontroller applications.
Let the blazing speed of the SX propel your next project
into the 21st century.
Fastest 8-bit Microcontroller in the World

50 MIPS Performance
  DC-50MHz operation
  1 instruction per clock (branches 3)
  20ns instruction cycle, 60ns interrupt response

E2 Flash Technology
  In-system programming via OSC pins
  Internal access time of 12ns
  E2 Flash rated for 10,000 cycles

Fast Interrupts
  Hardware context save/restore of PC, W, STATUS, and FSR
  Jitter-free 3-cycle interrupt response to RTCC rollover
  RB pins provide interrupt/wakeup-on-change

Flexible I/O
  All pins individually programmable as inputs or outputs
  Inputs are each TTL or CMOS level selectable
  All pins have selectable internal pull-ups (~20kW to VDD)
  RB and RC inputs each selectable as Schmitt Trigger
  All outputs capable of sinking/sourcing 30ma
  RA outputs have symmetrical drive (same Vdrop +/-)
  Analog comparator on RB (RBO out, RB1 in-, RB2 in+)

Component Reduction
  Internal oscillator (off, 4MHz-2^ 0-7 +/-8%) lowers EMI
  Built-in brown-out detector (off, 1.5V, 2.5V, 4.0V)
  Power-on-reset, multi-input wakeup

Designed for PIC16C5x Compatibility
  Ten new instructions for improved code efficiency
  New high-speed interrupts that are easy to use
  Selectable 8-level hardware stack
  C flag fuse-selectable as input to add and subtract operations
  W mappable into RTCC space for increased accessibility
  Code memory is run-time readable (fast lookups &  98 UL compliance)
  E2 Flash and RAM are fuse-reduceable to model  54 through  58
  Turbo fuse enables divide-by-one execution
  Order-of-magnitude performance increase @ fractional power per MIPS

General
  E2 Flash code memory - 2048 x 12
  RAM registers - 136 bytes
  Operating voltage - 3.7V to 6.25V
  Only 12mA @ 50MHz, 5V
  DIP-18/28, SDIP-28, SOIC-18/28, SSOP-20, and SSOP-28 packages
  Complete tools available free from Parallax, Inc c.
