Thanks to our ever helpful forum member epsilon, we have yet more of Dengeki's interview with Nomura to show you. Square-Enix announced at DKS3173 that the Final Fantasy XIII demo will be packaged with the Advent Children: Complete blu-ray release in March next year. Unfortunately for everyone outside of Japan, the demo will probably arrive much later than that.
Nomura has told Dengeki though that the Final Fantasy XIII demo may be sold separately some time after Advent Children: Complete's release. Square-Enix know they can make a huge amount of revenue by including the Final Fantasy XIII demo with AC:C but is selling the demo separately possibly taking it too far? The demo is supposed to be 90 minutes long, so the file size could make it unfeasible to host on the Playstation Network but if they sell it for an extortionate price, would people still buy it? I can pretty much answer my own question and say yes but that doesn't make it right.
Other than this, a few more details about the compilation were discussed which I've listed below:
All of the Final Fantasy XIII titles are based around extremely fast combat.
Final Fantasy Agito XIII will have both command input and action elements in it's gameplay.
Characters in Agito will actually transform into Summons. (misunderstanding) Each character will have their own individual summon.
Agito is currently running on PSP hardware but won't be released until after Final Fantasy XIII and Versus because of the lengthy story and large amount of characters.
大概意思是野村确认可能将与FFVIIAC蓝光版发售之后，再单独发售FFXIII的DEMO，FFXIII游戏的战斗速度很快，而Agito的游戏过程中也将有指令输入与动作要素，Agito里的每名角色均可以使用自己的召唤兽等等，因为故事的缘故，Agito将于正传和Versus之后发售。红字部分提醒了我们SE的JS本质


We all k now that the Final Fantasy XIII(PS3, 360) demo will be packaged with the Advent Children: Complete Blu-ray release come March next year. What we did not hear then at Square Enix' DKS3173 event was that it may be sold separately after the Complete's release.
That's the buzz we're getting now from Final Fantasy-XIII.Net, armed with Dengeki's interview with Nomura. It's kind of preposterous to hear of a demo being sold separately, but the demo is said to be 90 minutes long, after all. The sheer size of it makes it impossible for the PlayStation Network to host it. Still, will people bite the bait and buy?
Anyway, nothing else is completely final at this point regarding the matter, although there are a few more details on the compilation:
All of the Final Fantasy XIII titles are based around extremely fast combat.
Final Fantasy Agito XIII will have both command input and action elements in it's gameplay.
Each character will have their own individual summon.
Agito is currently running on PSP hardware but won't be released until after Final Fantasy XIII and Versus because of the lengthy story and large amount of characters.
Very juicy, indeed, eh? We'll get back to you as soon as there are more updates on this.
某站的观点 FFXIII(P3,XO)的DEMO将随明年3月的"FFVIIAC"蓝光完全版捆绑发售，SE的DKS3173并未透露什么太多新闻，不过在FFXIII官网最新的野村访谈中得知了这个消息。单独发售DEMO似乎是很荒谬的，我们也得知DEMO游戏时长为90分钟，是可以通过PS网络进行下载服务，谁知道呢？

卖Demo？

反正没三红的事

gt5的demo卖了200多w，还不断更新，ffb的demo能更新成正式版么
