Im curious... (tech specs question)

I don't know much about SKUs, but I know additional published copies cost a lot. It's probably not cost effective to add more SKUs to the release of the game.

We're already looking at 5 versions at launch, which seems like a lot to me as it is...and it always makes me nervous when a game tries to be -that- multiplatform. We do thankfully have Armature doing the Wii U/Vita ports.

I can't speak strictly from a tech standpoint, but I do know that Guilty Gear Xrd uses Unreal 3 and has to take a few dips quality wise to work on the PS3. Bloodstained is using Unreal 4. This may not be an issue, but I could see it...

We're also looking at a game that will be coming out some time at least well into 2017. I do think the PS3 will still be around then, but sales and marketing by that time will be certainly further down than they are now.

Don't get me wrong, I still feel like I prefer the PS3's experience overall. I like the controller better, the simplicity of the UI and how it still feels more like a "game" system than some kind of social, always-connected platform that everything is trying to be. I do however want what's best for Bloodstained though...

I believe it would require too much extra work to make another port, also i believe it would require intense game adaptation because of certain limitations (remember we are using state-of-art engine, Unreal Engine 4), specially the RAM limitation of PS3/X360 since they use only 512 RAM of the whole system which means there is only like half (256 MB) for games compared to 512 MB dedicated RAM on PSvita. Of course there is the CPU/GPU set as well that may lack the power and/or needed instructions for that.

Even if these system are able to run it, it may require a lot of tweaks and downgrades. I believe a much more interesting future port would be for the Nintendo NX, but only after at least one year after the console launch so they can understand how it works and what it is capable of, and of course to watch the console reception around the world. A NX port would be great for the Bloodstained sales, after Bloodstained proved to be successful on the market on 2017 release it is just natural to port it to the current gen consoles (NX) from 2018 onwards.

PS3 and XBOX360 are old console. Probably they didn't make PS3 and XBOX360 versions to push PS4 and XOne sales.

It could be made to work on last gen platforms if they really wanted to make it work given PSVita and Wii U don't naturally support unreal 4 either and Armature is "making it work" with some backyard engineering. However I think the reason they didn't decide to support them was because the game is scheduled to be released in 2017 and those consoles are already long past their expiration dates. Most people who owned those platforms have upgraded by now, or at least will upgrade by the time it launches which makes those releases kind of redundant.

A PSvita version has portability and it will no doubt sell well in Japan given how much they love their portables. As for Wii U it still has a small army of Nintendo loyalists who tend to eat up games of this nature so I would expect that to be somewhat profitable as well.

I know you're asking because you don't want to buy a new console. However, the PS4 has been out nearly 3 years at this point with an upgraded version on its way. That's half the life of your typical Nintendo console.

New hardware comes in, and it makes no monetary sense to keep developing for the old. I would understand if Bloodstained was targeted to release right near the end of the PS3 era, however we'll be half way into the current generation before it's done.
