As you already know, Publish0x has a banner announcing "In a few weeks, Publish0x is switching to [the] Optimism Network".
Well, I don't know about you, but my definition of "a few weeks" (three to four of them) is clearly different from those of the powers that be (tPTB). That banner's been up for over a month now, with nothing forthcoming, as far as I have seen. I'm starting to wonder if it's actually going to happen this quarter (or even this year). It certainly hasn't happened within "a few weeks". My optimism about it is definitely starting to wane.
Don't get me wrong here: I'm hoping to withdraw what ETH, AMPL and SPOT I've earned here before the switch over (and almost have enough to do so), so it suits me fine that this promised change hasn't happened yet and is dragging on. I would definitely like to know the timeline, so that I can postpone withdrawing to as late as possible, if possible. However, it definitely looks like another case of "long on promises, short on delivery" (LOPSOD) from tPTB ... No surprises there, then.
