FFX. PS2 exclusive. Released within the same window from the PS2 release as we can assume will be the time windo FFXV releases after the PS4/XB1 release. Total sales: 8 million

FFXIII: Multiplatform. Total sales: 7 million.

This is not "broadening the audience". I've been saying this since the PS3 lost a bunch of 3rd party exclusives back in 2007. This is merely splitting the audience. Look at every big game that was exclusive to the PS2, then look at the PS3/360 sequel or prequel. The multiplatform edition almost always sells on par or below the previous iteration.

Now look at the exclusives on the PS2 that stayed exclusive on PS3. Sold right about the same, maybe more. MGS4 is a prime example. God of War is another.

So to say that making it multiplatform will "expand the audience" or "help recoup development costs" is, factually shown to be, utter crap. The last generation showed us that if a game is going to sell, say, 6 million copies, it's gonna do it by being exclusive or it's just gonna sell 3/3 or 3.3/2.7 being multiplatform. Either way, the number of total copies sold isn't being increased whatsoever

No worries, maybe we'll get Final Fantasy Crystal Chronicles Crystal Bearers 2 and Kingdom Hearts 0.5 HD remix.

As long as it isnt Crystal Bearers 2 and plays like the first one but with online multiplayer I will be happy to get it on the Wii-U ;o

That comparison is a bit skewed, at least in regards to FFX -> FFXIII when it comes to exclusives to multi plats decreases. If you wanted to compare in relation to FF games, you'd have to use FFXII, which is sitting at 5.95M, below FFXIII. 

While I'm not saying that you're correct or wrong in regards to the outlook of other exclusive -> multiplat sales, you have to take in account a lot of other factors. Series over-exposition, decreasing quality, bigger availability of similar or higher caliber of games in equal genres, etc, etc. 

I chose FFX because it's a JRPG that released a short time after the PS2 released, and I think we're led to believe that FFXV will be similar in that regard.

But there are more examples.

Devil May Cry: averaging 2.5-2.7 on PS2. Sold on par with multiplat DMC4

GTA: SA: sold 20M on PS2. Sold on par with multiplat GTAIV

Tekken: averaging 3.5-3.7 on PS2. Sold on par with multiplat Tekken 6

Hell, even the WWE Smackdown games were averaging around 3 million exclusively on the PS2, then multiplat they sold on par or less.

Now look at the games that stayed exclusive

MGS: averaged 5.3ish million on PS2. MGS4 outsold 3 and is almost at MGS2

Ridge Racer: in the 1.3 million area on PS2. Sold similarly on PS3 (Ridge Racer 6 did negligible on 360, which could lead credence to the issue of brand recognition that doesn't transcend consoles like a Madden or CoD does)

In the 1st Party, Ratchet and Clank was in the 2.3 - 2.7 million range, on average, on the PS2 and the same thing happened in PS3.

I wish I had more examples for 3rd party exclusives, but a lot of them went multiplatform. But my point still remains. We have statistical data that the amount of people that are gonna buy a game is all but set in stone. If the game is on one platform, it'll sell that amount on that platform. If it's on multiple platforms, it will still sell that amount with just different distributions amongst the multiple platforms.

I don't see how game companies haven't noticed that in the last 8 years and still go mutliplat to "expand their audience" when it just flat out doesn't happen

 Edit: you can call it being butthurt, but I'm just offering a sound rebuttal to any sort of reasoning for it going multiplatform. Especially when you look at the sales of SEs games on the 360. FFXIII on the PS3 sold 82% of TOTAL SALES of SEs games on 360. 1 PS3 SE game sold 82% of the total number of SE games sold on the 360. Think about that and tell me how this is in anyway a "good investment" to put resources into the 360 versions of KH3 and FFXV. Hell, FFXII-2 was considered crappier and sold less than FFXIII and the PS3 version of XIII-2 sold more than the 360 version of XIII and comprises almost 40% of the total sales of SEs games on 360.

It's simply not logical to bring them to the XB1

You do make a sound case in those examples, but remember that also most of those games, which had multi plat entries on the PS3/360 era, were also of much lower quality than their PS2 exclusive counterparts, maybe except from MGS4 (review wise), from those that you posted.

I think one of the major reasons why multi plats from this gen trailed behind exclusives from previous gens was mostly due to lower quality. A lot of series dropped their standards (whether this was because of them going multi could be up to debate).

I agree that the biggest logic behind expanding the audience, at least on the publisher/developer side, is (in theory) to get equal sales between both consoles and thus a higher sales base. Since that hasn't happened with most cases, I agree that it's debatable as to whether or not the model actually works.

Isn't that simply because a lot of PS2 users went over to Xbox 360?
