After Microsoft's specification reveal for the Xbox One's impressively powerful 2017 revision, Project Scorpio, we look at five recent occasions when the lesser console was more popular and, in better news for the Scorpio, one where it wasn't.
Both the Xbox One and PlayStation 4 have been around for three years, and by most traditional metrics, they'd be only halfway through their lifespans.
But Microsoft and Sony have seen mobile brands replace flagship handsets on a more frequent basis and, signaling a shift in thinking, the PlayStation 4's 2016 refresh saw a novel introduction: the more powerful PlayStation 4 Pro.
Now it's Microsoft's turn after suffering in second place behind the PS4 and, were console wars lost and won on hardware specs alone, Project Scorpio would be a surefire winner.
There's a catch. Raw power is only one piece of the puzzle.
Look back to the less powerful PlayStation 2, for example, which leap-frogged both Xbox and GameCube sales combined.
Introduced in the year 2000, the PS2 tallied an incredible 155 million worldwide sales over the next 12 years.
Microsoft and Nintendo had an extra year to add new tech before their launches -- faster chips, more memory, and (in Microsoft's case) a centralized online multiplayer service -- but the Xbox racked up a fractional 24 million sales over six years; the GameCube notched 22 million in ten.
Before that, the earlier 32-bit PlayStation rocketed to 102 million by March 2005, while Nintendo's 64-bit N64 notched 33m sales during the same timeframe.
Nintendo is now considered an expert at upending power differentials: the comparatively modest Wii, DS and 3DS surpassed the Xbox 360 and PlayStation 3, the PSP, and the Vita respectively.
That said, there's hope yet for the Xbox Scorpio, the world's most powerful console, as it approaches a late 2017 release. This generational tale of David and Goliath found an exception in the Xbox One's rival, the PlayStation 4.
The PS4 had a distinct edge over the near-identical Xbox One, with faster operational memory and nearly 50% more graphical power.
By November 2014, a year on from launch, the PS4 was leading the Xbox One by 14 million to 10 million worldwide sales. After that, Microsoft stopped publicly reporting total unit sales.
Crucially, power wasn't the only difference between the two machines.
Xbox had been rocked by a disastrous Electronic Entertainment Expo, with Sony's PlayStation taking full advantage.
Ahead in spec sheet comparisons, the brand was also seen as more generous and more genuinely enthusiastic, more in-touch, less expensive and better value than its longtime rival -- an incredible turnaround from the PlayStation 3 days.
That gives Xbox a challenge in the run-up to the Scorpio's launch, given that a higher price point is all but confirmed.
Yet, at launch, the Scorpio could represent incredible value against equivalent PCs, the thousand-dollar set-ups that pushed 4k gaming into the mainstream and met the strenuous demands of virtual reality.
It's exactly that sort of true 4k fidelity that Microsoft is expected to push when all eyes turn to its presentation at 2017's Electronic Entertainment Expo in June.
