AMD originally wanted a brand-new architecture (the first since Radeon HD 2000 series) on TSMC's 32-nm node, and it was codenamed "Northern Islands." Then they hit a snag: TSMC cancelled their 32-nm, instead deciding to go straight to 28-nm in 2011. At this point, a new family codename called "Souther Islands" came about; apparently it was still 40-nm, and would be a more efficient version of "Evergreen" (Radeon HD 5000 series).

This is not true. The upcoming Radeon HD 6000 series IS "Northern Islands" and IS a brand-new architecture. After the 32-nm process was cancelled, AMD moved "Northern Islands" back to the 40-nm node (obviously it probably lost a few shader/texture/pixel units to what AMD had planned for 32-nm), and also started work on "Southern Islands." The "Southern Islands" family will be a 28-nm die-shrink of "Northern Islands" and will most likely be manufactured at Globalfoundries (though it could still be TSMC, or even both)
