Personally, no. I think it's much too early. Yes, sometimes when you play 4th gen, then look at 3rd gen, it might look old and kinda primitive, but it's actually not that bad. It's fine as is. Yes, there is the internal battery, but I'm pretty sure that it doesn't corrupt the data unlike with G/S/C, which I think was one of the big factors that a remake was needed. It took ten years for G/S/C to be remade, and it's only been about seven years since R/S/E was made. But then again, it took eight years for Nintendo to remake R/G/B/Y, so that is a contradiction in that statement.
Speaking of FR/LG, if they remake R/S/E, might fans request a remake for FR/LG? A remake of a remake? Then we'll have a remake for D/P/Pt? Remakes of HG/SS? It'll be a never-ending series of remakes and remakes of remakes. Though, maybe that's pushing it a little too far. Let's just ignore that statement.
The point is that it doesn't feel right to do it just yet. Maybe a little longer. It just feels much too early to make a remake of these games already. I love R/S/E, and I have nothing against these games, and if they made remakes, whatever, I'll go with it. I just think it's too early to do it.
