Is there any team behind classic yet?
Yes, Vitalik and his team will be programming for ETC. Any work produced by them can and will be applied to ETC so long as it isn't code that censors transactions (ETC's primary criticism of ETH). Tone Vays explained this in the video by Chris Ellis posted above. This is a major reason why it is likely ETC will stay around and may potentially grow much bigger than it is today. The development team
is ETH; it is not a rudderless ship as many claim.
That would really be bad for Vitalik and the Ethereum foundation. All their work and their ideas will automatically added to the competitor and there is nothing they can do about it. What would happen if the developers abandon Vitalik and the foundation and develop directly in the original chain? Will that kill the fork?
