Look at the github commits for the past few months.
No real new developments (to the core source code).
Don't forget that developments are made on multiple branchs...
I'm still holding. That was just my biased opinion. I understand that it's a lot of work to implement v6 and only 1 or 2 developers that have other commitments.
I noticed Herman did a number of commits today. Testnet v5.4b
