Tough to say. It always sucks when the original creative people behind something leave it to others. The new folks may to great but if you really liked the show for what it was at its inception then you might not want to stick with it and its "new direction".
I came into it in November right before the start of Season 3 and I have to say while I agree the show could be facing dark times ahead, I just can't get angry over it. Its a kids show and a cartoon, I don't judge any cartoons like I would judge lore or story from things like Breaking Bad or Mass Effect. I feel that if you start to do that you are just setting yourself up for disappointment. It is still fun to discuss it though, and I've had many laughs while doing it, so in my eyes that makes it worth it for me.
Sleepless in Ponyville was a masterpiece, there is just no getting around it and Keep Calm and Flutter On was also well done.
Also, before I go. Think about something, yes Hasbro and the writers will probably move away from whatever direction Lauren Faust might have had, but for them to deliberately want to kill the Brony fandom, that just seems inconceivable. The whole negative stereotype of 40 yr old dudes in the pink idle of Toys R' Us.. I get that, and I get how people think that is strange but does anyone really think Hasbro would deliberately throw a wrench into something that is making them a substantial amount of money over a possible negative stereotype attached to the franchise? The fandom has been around for 2 years now, if it hasn't happened yet it probably won't happen. Besides, there have been studies done stating that majority of bronies are males in their late teens and early twenties. *shrug*
