Hope I'm not jumping the gun, or pre-empting any official discussion, but I'd like to offer my (non-wish list) suggestions for Drupal 8, which is aimed at making it more consistent and more flexible.
Deprecate nodes
The problem I have with nodes, is that they come with a lot of baggage and inflexibility. I don't run a blog, and have never needed "posts" to have an author, revision dates, option for comments etc. And consequently there are a thousand modules required to "override" their inflexibility.
Replace nodes with "records" based on CCK, Views, Rules, Theme template engine
I'd like to see Drupal 8 based on core Fields, Views and Rules, and modules based around them. The huge advantage of this, is flexibility. For example, a node title is special text field that must appear first on a page. If a node title was a a standard CCK field, it could appear in a different order on a page, or even be a date field. I see Drupal 8 to be more like a standard relational database.
Extending CCK
I envisage CCK fields being a bit more flexible, so that I don't need new CCK modules. I should be able to define my own CCK data field formats, specifying how the data is verified, formatted and displayed. All we're really doing is displaying collections of data objects.
Modules
Modules would typically predefine and simplify the presentation of CCK, Views etc, and more advanced users could easily modify the CCK and Views set-up.
Pro and cons
I know this will affect how existing parts of Drupal works, eg. Permissions, but again, this is only another kind of content type. Blocks: why aren't these "nodes" of content type "blocks", etc.

D8: Better image handling
From the user's point of view, I think that Drupal's handling of images is poor. There are a lot of great modules out there, but out-of-the box image handling often have some features, but misses out others.
Great Features
Poorly handled features
While all these can be done, it is very very difficult to set-up, and tricky for an end user to use,
File System and File Management
I'd like to see a simple option in set up - files are uploaded to user directories.
I'd also like to be able to set "if content deleted, delete files" or perhaps (if that is hard re files used by multiple nodes) a tool to "find and remove unused files".
Views
Can we finally include Views in core.
Wrong place
You guys do know that all development and discussion happens in the Drupal issue queue and that almost no developer looks at the forums?
I advise you to find the relevant issues in the queue and add your ideas or voice your support.
That said, Drupal already has what the parent is requesting (node-lite objects), and those are entities.
Drupal 7 has a very basic Entity API extended through the contrib module of the same name, while Drupal 8 will have a much more advanced Entity API, with parts already committed to git.
Image handling can always be improved, and a WYSIWYG editor is something that is commonly mentioned, but rarely worked on. Maybe you will be the one who finally makes it happen?
Views in core won't happen for D8 because many things need to happen first, some of which are handled by the Drupal 8 core initiatives (the Configuration initiative and the Web services - WSCCI initiative are relevant here). There's a relevant core issue on that which you can find.
