That's pretty awesome, but I definitely don't have that kind of disposable income. One system upgrade would be the max for me.
The thing is, as was the purpose of this thread, is that the PS4 Pro is the more prudent decision because, currently, the PS5 hasn't confirmed full backward compatibility to PS4, let alone PS1/2/3. That, combined with Sony's own admission that the first generation of PS5 games will likely have PS4 releases, means if I upgrade to a PS4 Pro, then I would basically use $400 to milk an additional year or so out of my PS4. It's still really only a very incremental upgrade though. Speed and power, but that's about the end of it. I actually wonder if just changing my current HDD to a SSD would help maintain the speed at a fraction of the cost.
The XB1X, however, is so far and away more powerful than the base XB1 that it makes more sense to upgrade that system. The question is, however, is it worth upgrading the system when, less than 9 months from now, the XB Series X will release, essentially replacing the 1X. Is it worth $300 for 9 months? That's essentially $33 per month to upgrade the system. Likewise, I wouldn't even trade in my base model XB1 because the amount I get back for it ($75) makes it more worthwhile to keep it as a living room media/streaming center.
So I'm still trying to decide if I should upgrade one system or the other, or even upgrade at all. There are pros and cons to all 3 decisions.
