It kinda says it all right here:

Here is a blurb from that article just so you can see:
"Fishing, however, will not be retaining its previous functionality. I asked Yoshida whether fishing will have more tradeskills using its harvested items in the revamp, and he replied that the team actually went in the opposite direction by making fishing focus on the experience of fishing. If you like to fish, you can enjoy it as a hobby with its own merits rather than simply feeling it's necessary for a crafting class."
That article is current when Yoshi and Team were on the media tour in San Franscisco.
I took that to mean fishing will have to merit what so ever and just be a hobby. Might be fun but no progression what so ever. That means if your looking to make money fishing forget it. My guess it was to kill RMT's. Or at least make another attempt to.
