Ok, just because you don't like it. Doesn't mean you gotta be a negative nancy.
You don't see me talkin shit about The Elder Scrolls every time there is something mentioned about that. (Which is something I don't like. But doesn't mean I don't want it made;or for it not to exist; so people who like it can't enjoy it.)
A remake of FFVII would really be bought up like hotcakes and sell like they've been wanting their other games too. They can't compare all sales to the original FFVII,because it's really a fluke that it sold as much as it did. Sales =/= quality of game. Just as popular opinion =/= quality of game.
But really they gotta be full of horseshit. They are probably just making this up as an excuse to make it look like they can't do it.
Really, all they need to do is establish the artstyle they will use(Which would likely have to be in line with Advent Children and the other newer entries) for the 3D graphics. Re do all the assets for the modern age of 3D(Just use modern tools to bring the old to the modern), make the game with a classic mode (plays the game in the same old overhead view angle and uses text boxes for dialogue with toggleable voice acting for those that do and don't want it) and a remake mode(That plays the game with a camera akin to Crisis Core or FFXIII and uses cutscenes with subtitles and toggleable voice acting). Not change the gameplay or it's mechanics at all. Include the original PSX Midi driven Music and a re-recorded soundtrack that is done without major embellishment and uses all the same style instruments but do as much as possible live(Some stuff such as programmed synths and effects of course wouldn't have to be live)
But also: They can't simply do this game like other "HD Remasters" (Which is also the reason why MGS1 was not made into HD) because the base game hasn't aged well visually. They can't just take the game and render it in a higher resolution with a different aspect ratio and call it a day. People would complain that it still looks bad. And it would. The reason why PS2 games have been successful is because the games had more potential beyond the resolution limitations of the hardware and era. Which is why Some HD ports like GOW or MGS look better than others, simply because the original looked that good or had that much potential hidden by the resolution limitations. And why others don't, like DMC or RE4 HD(Which the PS3 version seems to use the PS2/PC versions as it's base. Which is heavily downgraded from the Wii/GCN versions. But also because the original artwork just doesn't have that same potential limited by the resolution of the original game. Thus they don't look as good when ran in a higher resolution.) Really, MGSHD or GOW HD don't look amazing because they redid the textures(like they often say they do. And they are full of horse shit when they do) because they didn't. It's just because the original looked that good.
Look at this

On the left is MGS3HD. On the Right is the PS2 version emulated via PCSX2 at a high internal resolution.
And here's another one, but this time full shots with the PS2 version being stretched to 16:9

The only differences being a different aspect ratio 1.)
And the lack of post processing effects like Bloom(which are disabled in PCSX2 automatically due to issues. If they weren't. I could use a widescreen hack to hack the game into 16:9 and have the bloom. And it would basically 99.99% the same as the "HD" remaster)
But I digress, in the case of FFVII, even more so they couldn't just "HD"-ify it because that means they would have to go back and completely redraw nearly EVERYTHING that doesn't take place on the world map or battle screen. Because the original game used Bitmap images for backgrounds. Thus they couldn't magically run this with a different FOV since the game didn't work that way. Ergo would result in "Work" which may be something that is basically impossible for them to recreate the original backgrounds due to not having the original hardware/software/people who created them back in the day.
