Nope. It's 1 wandering per server. I'd link you to the site where it's stated but it's undergoing maintenance or something, so this is the best I can do for now;

(It was also in a video somewhere, but it's too late for me to be bothered to find)

That interview seems to have already created misinformation regarding the primals 'wandering' the primals are still instanced the entrance is what wanders so i wonder if this is yet again misinterpretation of what yoshida said. Rpgsite has a newer interview that i would link but on my ps vita at the moment.

edit:

RPG Site: Primal fights will become roaming in 2.0 for the summoning system; are there any specifics you could go into? Will weapons and things like that still be obtainable, and will there still be instanced fights like which are available in the current version?
Yoshida: Most of the primals will not be “roaming” the public areas, and their battles will still be instanced, though it will be more challenging to discover these instances.
Koji: It looks like there was a little bit of misinformation given at the E3 interview (and this may have been my fault, or it may have been Yoshida-san’s). The implication given was that all the primals would be roaming, and once they were summoned, they would pop somewhere else in the world. This is not the case. While roaming primal are still not out of the question, the summonable deities will be instanced-based, with the primal going back to these instances once they’ve been summoned. However, players will still have to look for these instances once they’ve become available, preventing camping.

edit 2: it took me quite a bit of sifting through pages but here is the interview you and the newer interview were refering to and it quite clearly states one of each.

In 2.0 there will only be one of each primal per world. So one Ifrit, maybe one Shiva maybe one Ramuh, per world. These primals will be somewhere in the open world, roaming,and players will need to find them and then get together to defeat the primals.
