Normally would say Halo would sell the most but as the ps4 will more than likely have an even greater user base advantage over the x1, Uncharted could outsell it. It depends how many people get an x1 in the lead up to Halo's release just for Halo.
Zedla won't come close as it's not going to get any major sales with the low user base that the wii u has. Plus the x1 will likely have outsold it by then.
