Got mine a few days back...
Picked up GPD at Magic Mirror in Oakville, ON. I must say I'm impressed. I own all of the original PD1 stuff, but never really played it, as I found the system a little wonky.
"Powered by GURPS" seems like a good approach, as I can use all those GURPS worldbooks I have to throw some curves into an adventure.
As to the SFB universe, I really enjoy it. I've never played SFB, or any of the other games. My entire exposure to it has been as a fan of Trek RPGs of any kind. SFU is cool because they don't have to worry about consistency with an ever-changing TV\Movie series.
Of course, I've also picked up the FASA, LUG versions as well, and will probably grab the Decipher one in a few months too.
Great product, looking forward to all of the supplements.
