A spinoff crossover game with other 3 franchises being part of it. This consists of Blazblue, Under Night In-Birth, Persona 4 Arena and RWBY. One of them isn't a fighting game franchise but rather, it starts off as a western 3D web animation by Rooster Teeth. It's trying to pose as some animated show made in Japan but this looks more like some cartoonish game with 3D cell-shaded graphics made in Japan instead of the traditional 2D animated cartoon shows. The others have done well in mimicking the Japanese-style animation in an usual way when compared to Rooster Teeth which goes on an unusual route. There are some controversies surrounding the RWBY franchise like the main man behind it dropping out of high school just to do a bunch of animated stuff as well as getting hired by professional companies despite having a lack of diploma/degree and of course, some characters forging the educational qualification to enroll in the academy. Bottom line, STUDY GODDAMN WELL AND DON'T END UP LIKE THAT MAN WHO DROPPED OUT OF HIGH SCHOOL FOR THAT STUFF!
For Persona 4 Arena and Arena Ultimax, they are spinoffs of Persona 4 the RPG game but they aren't the only spinoffs so far. As Blazblue Cross Tag Battle is being made by Arc System Works, the assets for both Blazblue and Persona 4 Arena are quite the same. For Under Night In-Birth, the sprites will have to be redone although I don't know if the backgrounds from that game will have to be redone as well.
In comparison to Guilty Gear Xrd and Dragon Ball FighterZ which have brand new graphical styles, this for some reason is like one generation behind as Blazblue series started in the late 2000s so to the new consoles, the graphics are nothing special no matter how detailed they look. Sure, they are awesome as always throughout the Blazblue series although I don't know if the existing backgrounds will have high-res textures or what not.
One major problem, the character roster looks incomplete and upon the game's release, there will be 20 characters with the additional 20 except for 2 of them being paid DLCs. But at least, the game hasn't gone on the worse route. Street Fighter V when it first came out, was unspeakably incomplete in terms of character roster as well as the lack of important main game modes and the way to get additional characters is controversial. You can buy them as paid DLCs or you can grind in a tedious way to use in-game currency to buy them. In fact, I've seen the worst-case scenario regarding the rhythm games on mobile with endless paid DLCs for a complete collection as well as the initial amount of songs you'll get upon download completion. However, it seems that Cytus is going on a different route with free updates giving you additional songs at no charge and it may be the same for the idol-themed rhythm games. I don't know if the other game genres are having this similar bullshit as well.
Lastly, there will be English dubs in Blazblue Cross Tag Battle unlike Central Fiction which doesn't have one but the controversy regarding the lack of English Dub in Central Fiction isn't that large. Also, unlike the main Blazblue series, this will come out first on consoles and Steam.
