Five months later, and still no sign of any of these three albums in all the usual places (YJA, suruga-ya, vgmdb marketplace, ...).
If anyone here owns these and would be willing to sell, or happens to know any leads, please drop me a PM.
May I ask why you want these albums so badly?
5 months doesn't seem that long a hunt in terms of doujin collecting. I started following the scene in 2010 and was looking for Zephyr Cradle's Bifrost album at that time. I only just found a copy and was able to actually buy it this year.
My own personal philosophy has shifted on collecting over the years to if you can't get it when it is released don't worry about it and move on. If you find a copy later, great, but there's plenty of stuff in the present and future to take its place. Don't dwell on a hunt too much and instead work on your process of obtaining the items you want when they are released so you save yourself on time/money/headaches.
