Uhh looks good, just what i need. But why only two low-current 12V FET outputs for fans/LEDs?
When can I order?
There are two 12V FET outputs mostly because that's what is on RAMPS-FD, and there's limited current available on the 12V rail when running from 24V. There were zero of these outputs on the original RAMPS, so it's still an upgrade. There are also four buffered 24 mA 5V outputs for the servos that can be used as GPIO, and several other logic-level outputs that can be used to switch things.
As for ordering one, you can order the PCB now from OSH Park. If you want an assembled unit, it will probably be at least a few months, and that assumes someone decides this is worth building and selling. If that doesn't happen I may offer kits, but I'm not sure I can get the cost down sourcing parts for a small run in the US.
