IIRC Watch_Dogs launched on like 5 platforms no?
Yep (PC, X360, Xbone, PS3, PS4). Sorry, I wasn't super clear; I was mostly comparing Division to Destiny with the "3 platforms" bit. To be super clear, I don't intend to suggest Division will out-sell/ship/earn Destiny. I just think there's a lot going on surrounding the launch of Division that could propel it into a Top 10 new IP launch by any quantitative metric.
EDIT: Yikes, top of page post.
