No, at least for the moment. The new C3 features are not so breathtaking IMHO and I really don't like browsers.
Like many others, I too have a couple of C2 projects in development that heavily rely on 3rd-party-plugins currently missing on C3 (and some of them I'm afraid will not be ported oat all... ).
Maybe I'll subscribe in a future, when/if the C3 export function will accept C2 projects too, or C3 will suit my needs, we'll see
