Moving from GW1 to GW2 wasn't that big of a deal (for me at least). I only had time invested. In GW2, I have built up my account and characters to a point that I couldn't easily step away.
It would take much more for me to move from GW2 to GW3 and not take anything with me but a title or two.
I may take this as a sign to quit GW altogether. The company won't fold because of one person, but enough people like me quit and it will hurt their bottom line.
While I don't like the idea of a subscription, if we have to walk away from our GW2 accounts, I would be more for it if the story takes place as the next chapter of Tyria (our current characters included).
