Probably not, but the original game was still fresher in peoples' minds than it is nowadays.I don't recall JRPGs being the top selling genre since PS1 days. And those were FFVII and FFVIII.
I think even if this game was released back in PS2 or PS3 days they it probably wouldn't sell 10 million in 4 months.
I would be curious to see how many casual gamers, especially younger ones, are even that aware of it nowadays.
