So Nintendo has come forth and stated that the dock does nothing else but Laura Dale has gone on record to say that's not completely the case and that the Switch tablet will run at full speed when docked. Which even in the preview trailer the Switch games seemed to run better on the dock than in portable mode currently.
Also Nintendo has stated that they haven't revealed everything about the system and I believe they will sell some kind of enhanced dock that uses the SCD patent down the line.
