Nobody knows how long it will take for a jailbreak, but as there have already been proof of concept jailbreaks, I don't expect that it will take long after 4.0 is out.
I'm not sure what you mean, "is it going to be worth it". My take on it, is that Apple still doesn't expose enough functionality and requires jailbreaking, for some 4.0 will make jailbreaking obsolete.
With the release of the new phone approximately a month away, I'm surprised you decided to go ahead and ugrade to the 3GS. I've been telling my girlfriend to hold off since November.
