So they are transferring FFXI payment system to the same system that FFXIV is going to use which is Click and Buy/Crysta method. As stated in many posts::
C&B has a bad reputation.
Some only have C&B as an options
Come countries don't have ANY option
Some countries don't have the UltimatePay cards
Some countries can't use Paypal in conjunction due to issues.
So obviously people are unhappy about it. So, as you can see, this IS a current issue for the FFXI players who are very unhappy about this... and unfortunately a issue that we as FFXIV players will have to face as well.
