Credit to David from Capcom Unity for this interesting find: "I was looking at the networking specs on SSFIV 3DS edition

In the third paragraph it mentions the Friend Battle using the Nintendo Friend Code system:

"Play with someone who is on the competitor list by entering their Friend Codes (Internet play or local play). Register your friends on the list and enjoy the internet play easily!"

This make the third option "search for friends harbor" more interesting. It could mean a world-wide search against your friend code list.

I am now 90% sure MH3G will support Friend Code. It is probably one of the major reasons for Capcom to move to Nintendo and abandon Sony's AHP and Sony's reluctant upgrade of their NA/EU servers."

Might shed some light at the possibility of online play... We can only hope!
