Well, about the art style, there's something else to consider. In VC2, I think it's obvious why they went for the much more anime designs:
- The anime is relatively new, and it would what most people are more familiar with in terms of image association with the series, especially since VC1 is pretty old now.
- The PSP is unable to handle the full 3D Canvas engine cutscenes in the original, so to be able to present the same quality of scenes to the player, they got the studio which handled the anime to do the FMVs.
- To keep it consistent with the FMVs, they character portraits are now closer to the anime designs, and it also means they don't have to model and render higher poly models for all the characters for the normal word bubble cutscenes.
Whether the next game uses an art style closer to the first game, or the second game, will depend entirely on whether Sega feels the change in VC2 was successful in terms of art. If they want to keep the entire series more consistent, then they might well go with VC1 anime -> VC2 -> VC3. Even if the game is on consoles, they could still get A-1 Pictures to do anime FMVs.
Personally I hope that doesn't happen though. But if they do, it's not a huge loss either, because honestly I play the series for the charm and the gameplay. The actual storyline and presentation elements are pretty secondary to me.
As far as gameplay goes, I think it's really simple, and most VC fans will agree.
- KILL THE CREDITS SYSTEM. IT SUCKS.
- Keep all the new classes, if possible add more. The design team for the classes is really good, and I love all the additions in VC2. They're all unique and helpful in their own ways. Fun to play too.
- KILL THE CREDITS SYSTEM. IT SUCKS.
- Keep the enhanced and more detailed vehicle customization system. If possible I'm sure everyone will love to see naval and aerial vehicles as well. Setting the game outside of Gallia will be a good way of introducing naval units too.
- KILL THE CREDITS SYSTEM. IT SUCKS.
- I'll love to see an attempt to take the multi-map system of VC2, and combine it with the size of maps in VC1. Imagine for example the fortress map in VC1 where you fight Selveria, except there are various gateway camp entrances at the button and top corners which lead to areas inside the fortress itself, acting as tunnel shortcuts to surprise the enemy and also as alternate routes to approach to the top.
