I've just never seen console "reviews" before the console was even out yet.
I've seen reviews for consoles that never even got released. That was in the days of gaming news being entirely constricted to the magazine rack, but the concept remains the same.
As for the lack of games...frankly most console launches are f***ing terrible. The Dreamcast had the last console launch that would have satisfied me throughout the launch window on the strength of multiple great games. I'm punting on picking up either of these right away because of the lack of games, which is usually how I've handled these in the past anyway. The PS4 was the first console I got on launch day (Dreamcast had been out for a couple months) and it was used significantly less than my 360 or PS3 in its first year or so and I'd imagine much the same for these new consoles, so I'm punting until these consoles are more readily available before I even think about upgrading.
Even if I had stumbled into a launch edition of either of these consoles I don't know what the hell I'd be playing, other than slightly prettier variations of the same games I can play right now. Yakuza: Like A Dragon is the launch game that interests me the most and I'd be completely lost in that series (for as much as I love crazy-ass Japanese stuff and live for turn-based JRPGs, brawlers/fighting systems never appealed to me so getting into that series has remained near the bottom of my backlog all generation).
