Don't compare the remakes of FF games that never sold what FFVII sold... FFVII still remains the best-selling FF game to-date worldwide, and second in Japan (below FFVIII)... And the money Square made on that title and all the merchandise around it is amazing...
I personally would love a FFVII remake, but i would love really more a FFVIII remake, just imagine the epic intro FMV remade for HD...
