Going by the information on Amazon.com, Nero 8 will be released in the US on September 1st and will be priced at $99.99. Considering we have yet to see an announcement from Nero and the release is less than a week away, I don't think this is going to happen.
More realistic are the release dates listed on Amazon.co.uk and Play.com. In both cases, Nero 8 is down for a late September release, shipping somewhere between the 26th and 28th. This is plenty of time for Nero to launch their marketing campaign and get the software out the door.
Ship date aside, there is still very little known about Nero 8. Will it include new features or just an overhaul of the graphical interface? Feel free to leave your comments and thoughts in the forum.
