Earlier this week, there were some reports that Toshiba had submitted their new 51GB HD DVD disc to the DVD Forum for approval. Some even went as far to say that the format had been approved and would be launched by the end of the year. InfoWorld has now reported that none of this is true. According to their article, Toshiba's 51GB HD DVD disc is still in development and has not been submitted for approval.
In the last few days a number of Web sites and blogs have reported the format has been submitted for approval to the DVD Forum and some have said that approval has been received, but Toshiba says nothing of the sort has happened.

"We're puzzled ourself by where these reports came from," said Junko Furuta, a spokeswoman for the company in Tokyo. She said Toshiba hasn't made any further announcements about the disc since CES, and it wasn't submitted to any steering committees during this week's DVD Forum meetings in Tokyo.

When Toshiba first announced the disc in January, it said it hoped to get approval for the disc some time in 2007.
Sorry HD DVD fans. It looks like Blu-ray still has the upper hand in regards to capacity, at least for the time being. If you'd like to read more, the entire article can be found here.
