I know there are some user made stencils already, but with all the new hardware and especially the rackmount hardware I would hope that MikroTik could produce some official stencils.
Is this likely to happen?
+1.
search the forum, there are some already in here
Do you mean these? http://forum.mikrotik.com/t/attached-mikrotik-visio-stencils/27407/11
These do not have any of the new products such as RB1200 for example.
