About six years ago, the Royal Shakespeare Company presented a performance of Edward III and attributed it to Shakespeare.
It's accepted that Shakespeare didn't write every word of every plays in his canon (for example, he didn't write most of Pericles and Henry VIII) but there was obviously enough evidence for most Shakespeare scholars to accept that he wrote a substantial part of it. This latest piece of research is just a further piece of evidence, but it's nothing radically new.
