"For the purpose of this guide, any game console newer than the Wii is not a “retro console” because you can easily use HDMI to connect them to your TV."

PS3 was released in NA on November 17th 2006 BEFORE Wii was released on November 19th 2006, which makes PS3 retro console according your definition since PS3 is older than Wii, so maybe next time don't name specific console and just say you consider everything without HDMI a retro console.
