Last time he mentioned it (a few months back) he said he was still planning on releasing in 'one day'. I'm not sure if he'll bother though because it looks like the FPGA Arcade will be released soon and that will do much the same as what the CloneA was supposed to do.
That depends on what else he might consider for CloneA. I like some features of Natami board, the PCI slot for example, that FPGA Arcade lacks. But I don't think we expect to be able to put anything else in the FPGA other than what Natami team puts there, so we can't play around like we could with FPGA Arcade. (I'm nto saying Natami team shoudl open-source the inside-the-FPGA HDL stuff, but I'd love to know what things hook to what FPGA pins so I could put somethign completely different inside there and play around) Really, the only reason we care about FPGA Arcade is because we can put Minimig inside the FPGA there. If not for that, there probably wouldn't be nearly as much interest around here. Some perhaps, but not as much.
If CloneA made more of a computer motherboard shaped thing, that could be very interesting compared to FPGA Arcade, like I think Natami's board is more interesting than FPGA Arcade board. But then openness/closedness considerations come into the mix too. I wouldn't ask Jens to open-source CloneA HDL, btu to consider allowing people to put other things inside the FPGA and have some fun, and document the board for that. (I'd love to see Natami do the same someday)
