"Why did Intel give a statement at the CC indicating the PC sales are expected to continue slowing down. I believe 6% for Q1 2013. "
Q1 is only part of 2013. Q3 and Q4 are holiday seasons and a number of purchasers will be delaying until Haswell is released during the year.
"It will be easier for AMD to take market share away from Intel and Nvidia"
"This is already happening with AMD landing the new Wii U, PS4 & Xbox 720."
Intel is not in the Wii, PS4 nor Xbox. That did not take any market share from Intel. If the game consoles take market share from PC's, then these AMD design wins will do two things. They will cannibalize some AMD PC sales and some Intel PC sales. Do you think that the cannibalization will take place at the LOW end of the PC market (AMD) or do you think that it will take place at the HIGH end (Intel)? Businesses will not replace PC's with Wii consoles. At least I know that the company I work for will not.
I hope that AMD survives as an independent company. They have stumbled badly several times recently. Intel will have to help for them to survive. AMD credit rating was downgraded 3 levels recently. The cost of money for them is much higher now and cash will be tight for some time.
