You're misquoting me. You mentioned that the technical demo alone was not enough reason for a discussion or hint that a FFVII remake would be possible or could be coming in the future. I've responded by showing you everything that has happened then and since, and that it's all building up towards an announcement that they will be working on it, not that they have been already.
As for your last comment about not understanding the 360 situation. The reason why they are making XIII cross-platform in the first place is because the game will reach a larger fan-base, and they will make a huger profit from it. A FFVII remake would be viable enough just on the PS3 console, but if they are really going to utilize profit from this (as well as reaching both first time players and new ones) they would really need to make it cross-platform.
