That's assuming they'd do that for a jrpg that initially didn't sell very well.... I don't know...

I was stating before how most of the people who would pick this up would probably own a PS4 by the time the game is released (say 2016 due to it not even being announced for development). I think it might be a nail in the coffin if people couldn't just pick it up and throw it in whatever system is hooked up. If it released this year, or even next year I'd entertain the thought more.

If you could only do one system, it should be PS4 simply becasue its base is twice the size of Wii U and therefore it would be easier to turn a profit. Other than that you might as well do both if you can.

More people true, but I would argue brand interest. Being Xeno is now a Nintendo series, most PS fans don't care about Xeno as much. Meanwhile Nintendo fans would love to have access to earlier games. Keep in mind they originally released on PS2 (the highest usebase EVER), and the 3 combined didn't even sell 3 million.

I am a PSfan. I played Xenogears and Xenosaga and will eventually get a WiiU to play XCX.  In fact it is the single reason I want a Wii U.  If I had my choice though I would take Xenosaga on the PS4.  I know I am not the only PlayStation 4 owner who liked Xenosaga.  

So your assumption that PS4 owners don't care about Xenosaga becasue Xblade is on the WiiU is false. It doesn't erase my memories of playing on PS1/PS2

I'm a Nintendo fan and I've played Xenogears and Xenosaga. Facts are that most people who really want Xeno games are going to get a Wii U to play Xenoblade X ( which can also play Xenoblade Chronicles thanks to backwards compatibility, yourself included), but I wouldn't buy a PS4 for an HD version of Xenosaga. As a LOT of people have said, they are not going to buy a console for one game (or a trilogy, whatever), especially a remaster of a game people already played. There isn't a loyal Xeno army on the Playstation, and brand interest lies with Nintendo.

What I am assuming is PS4 owners don't care about Xenosaga because PS2 owners didn't care about Xenosaga, and there were a LOOOOOOOOOOOOT more. That's facts.

It will only be profitable when being released on 3DS.

Xenosaga 3D would be awesome! But low and behold, Bandai said HD remake.

As an important market for this game is japan, 3DS seems the most obvious choice. Should be no problem to remake PS2-games to 3DS.

EDIT: Ah I see, bigtakilla commented already that it was worded as an HD-remake.

Very true, but it's the HD part that kind of throws the idea out the window.
