Im sure the Canadian release date will either be between the US and UK release dates or same as US.
Ubisofts description of the game has just made waiting for the game even harder for me :p
Large Scale Naval Engagements: Epic naval engagements can be witnessed by players either firsthand or via radio messages and orders from high command.
Innovative crew evolution: Earn upgrades and experience to guide the evolution path of crewmembers, making your men the most effective naval force in the Pacific theatre.
Addictive Online New Adversarial Mode: Join forces with up to 8 friends via LAN or 4 via internet in either cooperative or adversarial gameplay modes. Scripted and generated mission types allow for epic online battles and unlimited replayability.
It all sounds so great. especially the Naval Engagement bit
