Just upgraded group set to Di2 and brake callipers to XTR, I can honestly say that there is nothing more I "want" to change other than fitting my summer tyres. Summer shouldn't be to much further away 
The saddle that came with the bike is so comfortable for me, I usually run a Fizik Alante VS but the giant saddle is as comfortable and lighter so no need to change it.

Each to their own I guess, 6 bolt 140mm floating rotors are few and far between so my options were limited. However I am more than happy with the design of the rotor, they perform and look good IMO which is all that matters.
I have the SL0 version which has Di2 already so apart from the saddle (Just could not get on with Giant neutral saddle) and the tyres (2 punctures in as many miles on second outing made my mind up for me to change them for something more resilient) I wouldn't change a thing.
Maybe the old pedals as took them off my previous bike and do not do the bike justice!
A few changes made since last pictures added.
Integrated handlebar/stem
Prologo Scratch 2 saddle
Seat post shortened
Stem lowered/cut
New Chain
36T Star Ratchet upgrade from the 18T (rear hub internals)
