The games that came out during their 'get-one-out-every-year-dad-gummit' phase were obviously rushed and contributed more and more to the worst design mistakes in the franchise. The command deck seemed like a band-aid for an undercooked system in and of itself-- Yeah, combos feel icky, barely any exploration, enemies don't seem to be reacting to much of anything and have no coded patterns... But look at all the sick shit you can do with commands! Thunder Surge! Fire Dash! This is variety!!
They very well may be going right into KH4, so if we see nothing for a long time, that's only a good thing. The hope is still alive for the next big KH game to be the best in the series.
