Just as curiosity, why do people say that snk having sprites on their games would be impossible because of budget? What was the real reason for them to decide 3d graphic style?

When people say snk should go back to xiii's sprite, they say it's expensive, and look I get it, that was in part the reason why they went bankrupt back then. Now, as an alternative people say why not guilty gear's graphic style? I go further, why not any 2d sprite?

Hear me out! Arcsys was also bankrupt when they made the first blazblue games, when they made xrd sign, they were not in a great shape either. So, my question, is made out of curiosity. What is really the truth? From 2010's we also have been seeing these kind of sprites that despite not looking as XIII's sprite, were not as demanding and also look good. Your average anime fighter have those, from phantom omnia, to nitroplus blasterz or even melty blood or under night.

Now, the purpose of this post isn't the average one that criticizes the actual snk graphic style, but to actually search for explanations of why those arguments have been around for so long, when they are not that consistent? I mean, if you see those examples, you can't tell me that team arcana had a bigger budget than many of the actual snk's titles, maybe even less than KOF XIV. So, either we are omitting something, or it was just a company decision rather than an economic one.
