Virtual Fighter REVO beta for PC is over, releases January,

I hate being confused. I just hate it. I hate that I can research something for hours, and watch tons of videos, and playthroughs, and still walk away confused. I think I have answers, but I'm trying to figure out what the difference is between Virtual Fighter 5 REVO, and Virtual Fighter 5 Ultimate Showdown Update 2.0. I am hoping the features are not just Steam and Rollback Netcode. So I went to the website, and here's what I found. It's a juxtaposition, and now I'm more confused.  

So is this what I'm supposed to be all starry-eyed about? Does the 2.0 update come with rollback? Are console players ever getting the 4k upgrade? Did Sega use marzipan for the icing on this cake? Was this a Sega and fans congregational decision? Why couldn't Sega just say "Hey everyone, Virtual Fighter 5 is getting updated to REVO on all systems, and it's going to be great! You can beat up your friends in 4K, with rollback netcode, and pop-off as much as you like." 

I need answers, Sega. I have a responsibility here. There are special editions coming, with different costumes, an anniversary sound collection, a legendary DLC pack, and more, but is it enough for me to want the Steam version if I already own the PS4 version? Is it?  I guess I'll have to wait until January 28, because I missed the beta. I was sick. Now you know too much, reader.
