I wonder why Capcom didn't decide to rebrand Iceborne as the usual Ultimate version we were getting alongside MH 3/4/Generations. Honestly, I think it hurts it's potential sales by a lot. Astral Chain even down by a lot, maintains it's hold in the Top 10 list.
Anywoo ! Switch is doing wonder on the back of the upgraded model we got ^^
The expansion is DLC and the retail release included the original game, we don't know what the digital sales look like, I think its far reaching to come to that conclusion.
