How much am I missing out on? Trails series question

I didnt even know they already had PS4 versions of them. Well in that case I suppose I can hold off for a while and see if they get released though it will probably be next year at the earliest since CS4 is coming out later this year and probably has all their focus. I have a big enough backlog to occupy my time with at least and worse case scenario I guess I could watch a Lets Play.
