They are likely to continue PS3 support in Japan longer than they do in other regions just for this reason. PS2 support for FFXI continued in Japan for longer there than it did in North America/Europe. I wouldn't be surprised if the next expansion has PS3 support in Japan but not for other regions, with it being phased out entirely by 5.0 (or at the latest, 6.0, but I think that's pushing it even considering FFXI's example--it didn't completely drop PS2 support until 2013).
