I don't necessarily mean in terms of sales; Sony has reported that they've shipped 1 million Move units in North America, and we've heard 1.5 million units have been sold in Europe. Plus, it seems pre-order sales for Kinect were high and in terms of technology and potential, both should – by all rights – have bright futures.
However, it appears both are encountering some definite issues during their first days. It seems to start off on a good note – Sports Champions for the Move and Kinect Sports for Kinect, which is dragging in decent review scores thus far – but then, games sort of go downhill. Take the competing fighting games- Fighters Uncaged for Kinect appears to be a mess, with a 2/10 from Eurogamer and a 4.5/10 from Game Informer, and Move's The Fight: Lights Out seems to be in the same unfortunate boat, with a 3/10 from IGN and a couple 5/10s from Eurogamer and VideoGamer. Then there's Time Crisis: Razing Storm for Move (trust me, other reviews are no better), which sort of implies that shooters with Sony's motion sensing technology could be terrible chores. On the good side, there are glimpses of cute goodness, like EyePet for Move and Kinectimals for Kinect.
But there are plenty of other downers. Kinect Joyride is mediocre with lots of 5s and 6s, Start the Party! for Move doesn't appear to be all that fantastic, and the less said about Racquet Sports (Move), the better. There are several decent games for both, coming in with average review scores of around 7, but it goes without saying that both applications require…well, a killer-app of some kind. Sony doesn't seem too concerned with sales numbers and Microsoft has already said that review scores for their Kinect titles won't matter so much. Indeed, the Wii is loaded with shovelware and never really did offer much in the way of top-notch software quality, and everyone loved it. So maybe the technology itself will be the ultimate selling point, and we have to wait for the AAA software.
Let's just hope it actually comes.
