You could try the search (through google - forum's is disabled atm), but in short: No, No and No.
I think the only one that posted some preliminary information that's not just based on pure conjecture or simulations is ASICminer with their BE300:
https://bitcointalk.org/index.php?topic=888260 .
Several companies have come out with just improved chips,
Bitmain's BM1384, for example.
Would be nice to have an overview of pure chips (bitcoin wiki, say - Canaan Creative make pretty good pages about their chips already), but overall.. unless you plan on building miners with them yourself, chip details aren't all that interesting compared to finished miners (be that hardware in hand / hosted / cloud).
