First off, FFXV seems to be holding off very well. (Going by Amazon). Game has released in Nov but will br counted as dec release since it starts off in Dec 1st week.
This gives the advantage of a monstrous FW sales followed by strong first 5 week sales.
Pokemon SuMo has been breaking records but the games released last month (we still dont have US numbers) and seem to continue doing well this month despite some retailers (amazon namely) shortages/sell outs.
Pokemon XY had done 750k its second month (nov) followed by 720k in dec.
Anywayzzz which will sell more? Long awaited FFXV (im guessing 1mil+ will be very easy with how strong word of mouth is) or will SuMo continue its huge Fad into the holidays?
Decide!
