This means nothing for FFXIV.
What it means is they cancled some games they had on the back burner to save money from their development so they can not list them as possible incomes in the future.
Forcasted income means they designed a game and forcasted that they would sell so many units of it based on features they proposed to release with the game. The problem stems that they decided to stop and look back at the quality of the games they were producing and some they were dissatisfied with. The quality of all game released reflects poorly on the company as a whole so they decided instead of trying to finish projects that have been deemed possible failures and just shoveling them out to try and make the money back on the software they are simply canceling the project and have to remove any forcasted income for that software.
This is most likely things like "My pony friend 3" I dont know why square decided it should release some of the games they did in 2009 and 2010, but I have a Pony friend 2 members code on my members account because I simply wanted the points. Got me into silver status for 2010 though.
In reality this information is probably a good thing because it means any project they have let remain active they have faith in performing at a phenomenal level. FFXIII was a financial success for them. a huge majority of the gaming press loved it. The few people who keep coming out screaming its not final fantasy and its not an rpg , and its not a good game are the same people who cry because Final Fantasy lasted longer then one game. They simply hate it because other people enjoy it.
The fact is FFXIII followed the recipe for Final Fantasy almost to the T. and FFXIII-2 will end up resolving the issues most people had. They already said they were taking the negative media against XIII to heart for its internal sequel. Again it'll probably sell at least another 3 million units and they didn't have the first time investment cost of creating the in game world and assets as a huge number of assets can simply be reused.
