I don't know if 11 'interested' people across the last 2 sculpts (to my knowledge at least, going from the 2 threads I've been involved in) is enough to warrant Anthony to keep going for us. I'm afraid there isn't much interest out there anymore with the series being done. I think a lot of 'us' have moved on, save for a handful.
I mean, even Jack who Anthony was BEGGED to sculpt and was the main character only garnered 12 interested boardies here. And if that thread is up to date with who paid, Anthony only sold 6 casts (including multiples to AllisonAmy) on the boards. Again, going off the info posted there. To be honest, I think it's a miracle we got any more out of him.
And to be clear, I'm not putting words in his mouth as I haven't talked to him about doing any more LOST sculpts. This is pure conjecture on my part based on what I've seen in these last few threads.
