I just did an approximation of rough math.
Say the PS4 sells 50K per week, that's 7142.85 units per day, or 297.61 units per hour. Now say Amazon sells 15% of that, they sell 44 PS4s per hour, and when split across bundles, we need to realize that the numbers aren't that impressive to extrapolate anything from.
Amazon is on average selling ~44 PS4s across all SKUs in the US. That means the Destiny bundle is MAYBE selling 20 per hour. (probably triple that during peak hours and a fraction between off hours).
