Sorry that I'm late to the Call party, but there's something that actually came to mind when I was thinking about how Call would be considered as "more robotic then Beck" and all that, and realized that maybe Call can be compared to Beck as to what a Robot Master can be compared to a Reploid in terms of emotions and other things. If I remember correctly, there were some differences, mainly the fact that a Reploid's personality and mindset can evolve over time, while a Robot Master is mostly just stuck with the personality that they were programmed with. If that ends up being what one of the differences between them are, then showing said distinction in-game would be... interesting, to said the least.
To put it another way, Call could be considered as Roll, and Beck could actually be considered as Megaman X, rather than Classic Megaman. That's my thought on the matter.
