I really think there's just so much they could do wrong with the re-make - starting with picking up every single current trend in gaming and slapping them into it, or trying to retcon everything to fit in with Crisis Core and Dirge of Cerberus (aka "All the Gacktesis All The Time"). Just ... no. Leave this one about Cloud and Sephiroth, same as Advent Children. Plus, of course, if they start stripping down the populations of monsters, or removing various weapon models and so on, I will be very disappointed.
Mind you, I suspect we have a couple of years to wait. I'm not expecting to see the remake before the 20-year anniversary mark in 2017 (they haven't given a date, but I suspect Squeenix marketing would be over the moon if they could meet that deadline. Failing that, 2018, for the 21-year mark).
Of course, if they do mess it up and remove a lot of the good stuff, I'll just sigh, sob, and go back to playing the polygon version on the PC and saying "what a pity they've never done a remake".
