We'll be revisiting full-screen functionality in a future release, but at this point we've announced that there won't be any new features for 1.0.
Note that you can disable the specialized VMware mouse in your virtual machine and return to the normal guest mouse, and the menu bar at the top of the screen will not drop down.

To customize the virtual machine's mouse settings for playing games, use TextEdit to make the following changes while the virtual machine is powered off:
In the virtual machine directory, add the following line to the end of the virtual machine's configuration (.vmx) file:
vmmouse.present = "FALSE"
In your home directory, add the following line to the end of the file ~/Library/Preferences/VMware Fusion/preferences:
pref.motionUngrab = "FALSE"
