A lot have been said on Apple's Mac OS X Leopard, especially when the consumers finally got to see it running during the recently concluded WWDC. The new operating software wouldn't be arriving officially until October but those in the know are already saying that a number of useful small updates will come with the commercial version.

Apple is quite known for doing this to its products - never really telling the consumers everything that has changed. Just think of it as a finders-keepers game from Steve Jobs and the rest of the crew. And when you really think about it, it's not really harmful. If anything, it encourages users to play around with the software, learning it fully in the process.

Anyway, until the official release date comes, we're still tagging these under Rumors. But it would really be appreciated if these turn out to be true:

• A new version of Quicktime included with Leopard will reportedly allow full-screen mode without a QuickTime Pro key, echoing the feature added months before to iTunes.
• DVD Player will also see a major update with an HD options pane for Blu-Ray and HD DVD discs as well as the opportunity to add DVD cover art and change movie region support on the fly.
• Sun's unique file system will appear as a non-default, read-only format out of the box with write support possibly arriving as a separate update in the future.
• ZFS in Leopard will support some of the trademark features, such as instant and low-storage "snapshots" of a disk volume, and cloned copies that can be modified with only a small penalty in terms of disk space.
• iChat may also have received a substantial upgrade: Those contacts with mobile phone numbers can be sent an SMS text message.
• Google's influence is also allegedly present in the instant messaging app and will let Google Talk accounts mix with today's AIM, Jabber, and .Mac users.
• Users choose the default IM program, similar to the way Safari is used to choose the default browser, and will also be able to explicitly share more than the Public folder on a network.
• Even Dictionary will have the choice of switching from the Oxford dictionary to Wikipedia.
