Cool! According to IGN these are 3D remakes so I assume they'll be like Final Fantasy III.
Though I have one request: release the original versions, translated into English, on the VC! Square Enix seems reluctant to release games on the VC that they figure they can re-release in some other form and charge full price. Fair enough. Sucks for us, but we can all see why they would do that.
The thing is though that I'd argue these are two separate, non-competing products. In fact they compliment each other. The original and the remake are different enough that it would be worth owning both, especially since we're talking about a shift from 2D to 3D. If anything the original versions would make a fine companion to the remakes. I don't think anyone but the most old-school purist is going to not get the remake because the original is available on the VC. If anything this would be a clever way to get people to buy two products. Konami released a remake of Rondo of Blood on the PSP and also included the original, which had never been released here. Well including both was very fan friendly (except for the PSP part

) but they probably could have gotten more sales if they separated them. Well that would be PSP and Wii which is not an ideal combo but DS and Wii certainly is.
Hell Square Enix could even charge a premium for these titles on the VC because they're imports. Meanwhile the translation was already done for the remake. You could probably get an American intern with no knowledge of Japanese to take the remake's translation and shove it into the originals. So they can charge a premium and get away with it despite not that much effort on their part and sell two different products. It's win-win.
