Yeah, that really blows. I'd love to get a CE that includes a Steam code. The website says the Premium one will be available for US and Canada soon so I'll keep an eye out. Hopefully that one will be available for PC but I'm not holding my breath. IIRC the EU still regularly gets physical releases for PC games so it probable just comes down to the realities of different markets...
If I start feeling particularly stupid, I might just get the console one for the extra junk and buy the game on Steam anyway. There's a leftover Xbox One Cyberpunk CE I spotted online that I'm currently trying to talk myself out of ordering...
