The question is, was ff xv only delayed because they need time fix some bugs? Or can it be that Sony and SE had a talk about the ps4 slim and to get the possibility to gain more sales with the new model? I mean this could be the bigger reason for the delay, because how much can you fix in to months, not that much i think...but the release of the new slim sounds more important for me, what do you think?

they made a clear statement it was for polish, every previewer that played it so far that I have read said the game still needs some work, so I do think there is truth in their statement, I don't think it was delayed because of hardware releases

The Slim might release next month and FFXV in November so i'm a bit confused by what you're trying to say in the OP.

No.

Games go 'gold' (discs begin being manufactured) before actual development ceases in many cases these days. That's why there are day one patches, to add the data and fixes that the development team have made during the time in which discs are manufactured and shipped. In this case, the development team made the decision to delay the game rather than release a substantial day one patch. It's unfair on the (minority at this point) of gamers playing without an internet connection, because they get one version of a game, and those with the patch get a technically better product. It's a good decision to release as good a product as possible rather than require a hefty day one patch.

That's right, so more people with a ps4, so more customers that will buy ffxv, wouldn't be surprised if there will be released a slim bundle with ffxv, and ffxv would profit from a release of a cheaper model before the games release

I know, and microsoft has already there slim, and to keep a good relationship with sony, for the future too, sony must do everything to show that the game will sell well on there hardware

No, and i don't think it will release this year, would be to much alongside the slim and the vr, plus i don't think the neo would help ffxv for sales, only if there would be a big difference for the game itself

No, that don't will be happen, but for SE is naturally to get the best results of sales for ffxv, and with a cheaper ps4 the chances are now better

Short answer: No.

Of course they havent delayed it because the slim is releasing, crazy suggestion.

What i'm meaning is, that with the release date, there will be more ps4 users, because of the slim. Because everyone interrest the first week sales of a game, so it's important that the time where the game release, are many hardware owners
