"Is that going to be a good thing or bad thing?"

It will be a very "good" thing for the vast majority of Steemit members (both present and future), essentially because most if not all of Steemit's worse abuses like @themarkymark, @buildawhale, and a few others in their band of criminals will be gone, with the curator reward system being restored to what it was intended to be like, and NOT manipulated by those few scumbags who wanted nothing more than to line their own pockets at the expense of everyone else.

It will however be a very "bad" thing for Steemit's corrupt management and its witnesses as both the Steem coin and the Steemit witness systems will be replaced by Tron's. Sure, a few Steemit diehards may very well try to keep Steemit alive after the fork, but that will more than likely fail miserably, with a very high probability that anyone left holding Steem at that point will loose most, if not all, of their entire investment. The wise move for members would be to get rid of whatever Steem they hold now before it is too late, and remember that it takes 13 weeks to power down Steem power into liquid Steem which can be transferred and/or sold. 13 weeks is a very long time to be stranded on a sinking ship.

"Only time will tell."

Indeed!
