Bulldozer will come under the names A4, A6 and A8 depending on model, these numbers will also be part of AMD's Vision-branding. AMD's goal is to make it easier for consumers with AMD Vision which is why Brazos, Lynx and Zambezi will be part of it instead of having alot of different models people need to remember. So A4 will be a Quad-Core, A6 Hex-core, A8 Octa-core etc...

This is what AMD are planning internally but are a subject of change, what is set in stone is a much bigger focus on AMD Vision. Unfortunately I wasn't the one to see the planned Bulldozer logotypes Will post here if I find out about anything else...
