There's a fairly extensive writeup by the designer, Monte Dalrymple, in the current (January 2006, #186) issue of Circuit Cellar.
True, still no on-chip memory, but there's an expanded register set and the external bus width can be set to 16 bits to improve bandwidth. There's a funky bit of code to get the thing booted before it knows what the external bus width actually is.
.... for which they've added a bunch of support for 32-bit operations.
