Not so much, GHash has broken the 50% barrier for sustained periods of time. The old news was they were a threat to but promised never to grow that much. Remember the public statements from them and putting a halt to independent miners joining? The unwritten news is they lied through their teeth and continued to add hashing power to their private stash. You do recall they were already caught once performing a double spend attack, correct? It is new news, a current problem if they continue unchecked.
