LeBron James' highly anticipated meeting with the Miami Heat in Las Vegas ended Wednesday afternoon, but his uncertain future remains.

According to a person with knowledge of his situation, James has not made up his mind about whether he will re-sign with the Heat or head elsewhere. The person spoke to USA TODAY Sports on the condition of anonymity because of the private nature of the talks.

The Cleveland Cavaliers are considered the most dangerous threat to the Heat's hope of bringing James back. The meeting included James, agent Rich Paul and Heat President Pat Riley and lasted more than an hour.
