Everything we ordered is now available with exception to Sand Green Wizard Staffs which should be on their way.
White Vambraces are on the list but due to budgetary constraints we had to cut a few colors out and that was one of them. You will see them someday though.
The Sand Green color has indeed been updated and it is like spot on. I actually thought I was dreaming when RedBean sent me the color samples because I couldn't believe how exact it was. I apologize it took so long to get right but without the exact recipe and materials TLG uses it takes a bit of trial and error.
RE: Chrome. We have a batch in the works but frankly, its just way too much labor to schedule a massive restock that includes every product we have. This weekend was busy enough

. I'm also waiting for a few more boxes from RB so I can add a few more things to the 'chrome' list like Legionary Helmets. If you have suggestions on what else you'd like to see chromed, please consider taking some time to post your ideas to The Forge.
The Trans Dark Blue is considered a permanent product of the BF lineup and is sort of our way of expanding our traditionally metallic-color weapons to the realm of magic. We are huge fans of AD&D and games like BrickQuest, BrikWars and BrickBattles and thought this would give players/minifig fans a new way of displaying and engaging their figs in battle with an added bonus. If the Protection weapons sell well enough we may run helmets/armor in Trans Dk. Blue as well so heros can have an entire Suit of Protection. Don't think we haven't thought of other Trans colors as possibilities as well!
