It is coming… to a forum near you!
Just noticed today while responding to a Moodle.org support forum (which you should totally do to!) that the attachment method has been changed to drag and drop. Drag and drop is mentioned as one of the new major features of 2.3 so if you are going to be upgrading to the new release, be prepared for awesomeness!!
Note: Moodle.org still has the 100kb limit on attachments on their forums. If you have been following my posts though, there is a workaround for that.
Update: Moodle.org is running 2.3 beta according to this post by Martin Dougiamas http://moodle.org/mod/forum/discuss.php?d=205214#p894952
