Ubisoft expects next-gen consoles to integrate 'item based model'
Beyond that, Guillemot expects growth due to two trends: first, "the forthcoming arrival of the next generation of consoles which will be increasingly connected and will strongly boost the market thanks to a new qualitative leap and the integration of social games benefits and the item based model," and free-to-play games.
The "item based model" sounds like a trend bleeding over from free-to-play games, in which games are sold for free (or cheap) and microtransactions bring in revenue through the sale of in-game items. We have seen this outside of the free-to-play world in this generation, in the form of costume sales and the occasional weapon unlock; however, if Guillemot expects it to be a significant source of income on consoles, it's likely to be even more emphasized in the next generation.
