Personally, I'd be more interested if the company has never had crossovers with the other companies before. That's why the main reason I'm interested in this game is because of Sega's involvement. This is the first time Virtua Fighter has ever been in a crossover with Tekken and Street Fighter. This, of course, brings in other Sega series that are also in a crossover with Capcom and Namco Bandai series for first time too.
I also think that with the numerous anime/manga licensing that Namco Bandai has, they should just make a similar crossover RPG with Shonen Jump characters in it.
Little Mac, Mega Man, Travis Touchdown for Super Smash Bros. 4. Street Fighter x Mortal Kombat, Shonen Jump vs. Capcom please.
SRW games are tactics game with long animations. Endless Frontier has more interactivity and control input. NxC has a primitive version of it. PxZ's combat system keeps making it more fun and less tedious, but it still has room for improvement in the future.(hopefully in another sequel).
