Since the node shrink rate is slowing, making more and more powerful APU's becomes much tougher due to dramatic heat output. Hence the reason the XB1X has vapor chamber cooling.
The PS5 will likely either end up a OG PS4 sized vapor chamber cooled APU (possible), or be XB1 sized with a massive standard heatsink cooled APU (unlikely), or be Pro sized with a separate CPU and GPU (possible).
With PS and XB making it quite clear they plan to continue this constant console upgrade cycle, a separate CPU and swappable GPU makes the most sense to me.
I guess there's always the possibility that they use an APU with a mid/high level CPU and low/mid level GPU and then design a slot for an upgradable GPU later on that either stands alone or even crossfires with the APU. Your probably looking at a OG PS3 or XB1 size box though, unless the upgradable GPU is an external plug in.
The hardware will allow for plenty of exciting gaming possibilities.
