I sent them an email a week or two ago asking for an update as well with radio silence.
I'm getting miffed about this too since I only use GW on my N3DS and don't want to bother with the other methods and having to move my GWemuNAND over to them. Over the past couple years I've seen the 3DS scene move so fast I'd rather just keep on what works rather than spend my entire weekends moving data and re-setting up my 3DS with the "new hax". It took me two years after menuhax was released that I finally installed it rather than opening GW via Ninjhax.
I installed A9LH on my O3DS but it doesn't seem to offer much over GW, and the fact it's working in sysNAND just scares me.
B9S seems intriguing, but now I see posts about game crashes due to region checking (and subsequent having to change region code in the OS for them to work = more time spent re configuring) which they work fine in GW emuNAND. If someone can share with me an intriguing argument and list of benefits of moving from GW to B9S I'll consider it, but right now I'm fine not updating since I don't have a choice.
