They will be very close, even with the rumored specs. The DDR3 vs DDR5 difference is not as big as the internet tells you, when you see a complete system. I think the consoles will be in the 5 - 15% more / less powerful than the counterpart.
So games like Killzone 4 will be easily possible on the next Xbox as well.
I will get the Xbox 3 anyway, because it will likely have the best games lineup and the best online experience again.
Imagine not having GamePass on your console...
