It has a lot to do with it.
The team was changed because they both had different visions on how to handle the remake, to ensure the highest quality possible Capcom decided to develop RE4 internally (or with the remake 2 team).
Even considering their respective releases, fans prefer Resident Evil 2 to M two Resident Evil 3, in terms of level design,story, controls etc
RE3 (if we go with the rumors) was a side project to prepare M two for RE4, but ultimately Capcom decided to make it with the main team
And i believe they made the right choice, we are going to get the highest quality possible with the most experienced team
