OMFG HAX
Look at some of the screenshots that we have. Notice how in many of them, Pokemon that are actually the same are in different poses. For instance, Munchlax walking/Munchlax sleeping, Cherimu (or whatever its called) in and out of its flower, Weavile standing and Weavile leaping, etc. Maybe Pokemon have different poses depending on whether its day or night. Hell, maybe stats could even be affected slightly (ex., nocturnal Pokemon such as Noctowl being more powerful during the night), or maybe even moves like Sing having a higher hit percentage during the night.
