So, from what I gathered, the higher wattage (power draw), mixed with the battery required for that and form factor that would likely stem from a result of it, makes shrinking the existing architecture unlikely for a while. Changing the architecture would make it possible sooner, but it would no longer really be a PS4 as games wouldn't natively function on it without some reworking.
Honestly, Sony is better either trying something new or capitalizing on what they've done so well this past gen over following what Nintendo is doing. I'm far more likely to buy two unique products than two that are basically the same thing anyway.
