So it's sales of the hardware that determine it's output/library- but we only count games going forward, ignore Nintendos relationship with third parties and the XBO's overlap with the PS4 (the market leader)?
Sounds like cherrypicking to me. Let's use the Wii- better first year than the 360 (outside of a preference for first party games), the 360 undoubtedly has the better and deeper library. It also sold far, far more games than the Wii.
You can't ignore common sense and patterns within the industry, then claim another users reasoning is flawed when you're clearly not looking at the full picture.
I can't tell why you're using the XBO's overlap with the PS4 against me, if that is what you are doing, as it only supports my point. The PS4 gets every notable multi-plat that the XBO gets, and even more exclusives. The XBO's library is pretty much the PS4's, and the PS4 goes beyond what the XBO has to offer. This only makes the Switch out to have an even better library (in its first year, yes.) There's no cherry-picking, two of the best games ever in one year, plus more of-note exclusives in one year than I reasonably can think the XBO has ever had.
The 360 and Wii comparison is not a pattern, it will not occur here. The XBO has already fallen much behind the 360 in its vast offering of games, as well as its overall sales output of SW and HW. Really, all we have to point to is the relatively sluggish sales of the XBO to come full-circle and note that what Ka-pi said is not mirrored in the general market, and therefore he is wrong.
