This last round of PS3 and Xbox 360 hardware revisions got me thinking: which consoles have had the most hardware revisions, and which consoles have had the least? I'm talking about differences in hardware here, not packaging or included titles. So, what say you? Which ones have had the most and which ones have had the least? Back up your claims with evidence in your responses and I'll update this main post with your responses! Any early guesses on which ones had the most and which ones had the least?
