How likely is it that Square Enix will make World Visit Data-Center Wide?

Considering Yoshida recently said how incredibly difficult it would be just to make a cross region Party Finder. I sincerely doubt World Visit even in the same region will never happen within FFXIV's life cycle.

To be fair Yoshi always seems to reffer to FFXIV as the most fragile yet complex thing on the planet. Yet there's always something "incredibly difficult to implement" that ends up becoming a thing after some budgeting. If it were to happen it would most likely be a Cross-Data focused on each region, like some said. But before that ever happens I feel like we might get cross-server market board, free companies and cross-world linkshells become the new default. I remember Guild Wars started with the whole servers being separated yet you could guest visit other ones. Then eventually the server data got merged and the only true separation is regional. I don't recall if it was the same with WoW though.
