will it confirm? Will it be dopped (automatically)?
It may take several days, but it will either confirm or it will be dropped. If it hasn't confirmed within a week, I'm almost certain that blockchain.info will drop it. Probably sooner.
ok, thanks for the info
So I will just wait... It is not an urgent transaction, so no problem
I also read something about importing the private key in another client and "removing" the broadcasted transaction. any thoughts about that?
If the transaction was sent with blockchain.info/wallet, then you cannot "remove" the broadcasted transaction. You have to wait for them to do that. They typically have done that after 3 to 5 days.
If the transaction was sent with Bitcoin-Qt, then you need to remove the transaction from the Bitcoin-Qt wallet (or stop running the Bitcoin-Qt wallet). Otherwise, Bitcoin-Qt will continue to re-broadcast the transaction forever (or at least it's supposed to if its still working correctly).
