Is it safe to update my Wii U? (Softmod related)

Hey,
I just got a Wii U and connected it to my Wifi.
Every time it wants to download and install the newest system update.

Im waiting (and hoping) for the Wii U - Softmod and im asking myself if its safe to update the system? Or if it will delay the use of a softmod because im running on a higher software version?

Thanks for your anwers!

No active Wii-U softmod yet that I'm aware of. You can keep that thing with dust bunnies, or you can use it until if/when things change (absolutely no idea if that'd even happen). Only the vWii side has been softmodded.

Mh..I will then update the Wii U in purpose of using the Nintendo Club - Thanks for your fast reply!
