AMD64 confusion

I am trying to get a grip on the AMD64 technolog and this is what I have come to:

Current processors

Opteron, three HT-links, 940 pins, 128-bit dual channel DDR333 ondie memory controller, buffered (ECC REG) memory
Athlon 64, one HT-link, 754 pins, 64-bit single channel (up to) DDR400 ondie memory controller, unbuffered memory
Athlon 64 FX, three HT-link, 939 pins,128-bit dual channel DDR400 ondie memory controller, buffered (REG) memory

Future processors
Opteron remains 940 pins
Athlon 64 and Athlon 64 FX starts migrating to 939 pins, 512 KB or 1 MB L2 cache, dual channel memory controller, unbuffered memory
What happens with Socket754 I have no idea

Does this sound correct or am I wrong? (trying to put an end to my current confusion). If above are correct what will be the
difference between Athlon 64 and Athlon 64 FX in future chips?
 
Athlon 64 FX is at 940pins now, but will migrate to a 939 design in the future. As far as I know Athlon 64's will stay with the 754 pin design.

Yeh.. the AMD 64 3x00+ series will migrate to 939 pin.. but the FX-51 is.. ATM.. socket 940.. same as opteron socket.

You have that backward... the AMD64 xx00 will stay socket 754... the current socket 940 processor will switch to socket 939. (at least, based on everything I've read up until now, that's how it will be)
 
Athlon 64 will be both 754 and 939 for a short time. Eventually 754 will become the "Duron" family (not sure about name) with 256k/512k chips using single channel memory.
 
Bloody hell. They are good chips, but its definitely a product you need to do a lot of research on before you buy.
 
Someone posted a link to a REALLY good roadmap not too long ago, it showed everything there, and also what each core was planned on including as far as cache and memory channels and speeds.
