yes. lots to worry about. the fact that the team basically ****ed over all the tweak developers. none had a heads up. a lot of them like chpwn are quitting the jb scene (goodbye zephyr, etc). the fact that the 'store' they got paid to include in the jb had repos hosting pirated versions of other developers tweaks, etc etc.
basically theres not much reason to jailbreak when some of the best tweak developers don't give a **** about iOS anymore.
There was word that geohot had all the components needed for a jailbreak as well. If he had released it all of a sudden, the situation may be the same regardless, with no time for preparation.
He released limera1n one day before the dev team's SHAtter for iOS 4, but the reason why it wasn't disastrous is because iOS 4.0 was already jailbroken with jailbreakme, so all the necessary foundations for iOS 4 jailbreak was already there.
When there's a race between two groups who BOTH have everything done for a jailbreak, giving any time ETA will just let the other group release theirs without warning ahead of time of the other group
Of course, there are probably more complications to the situation then what I am speculating.
About the tweak developers, yes, it's sad to see them go but there are still lots of great developers out there. It's easy to just blame and yell at others, but if you had been in their shoes, the decision would've been much harder for you
