I hope it has similar gameplay to Blood Dragon except not faux sandbox (go all out if you can do it right or not at all) and harder with many more enemies per set. FC3 and Blood Dragon have a good solid base but ruin it with populating the outposts and areas with next to no enemies, even with the reinforcements after screwing up a stealthy approach. But the AI and gunplay are relatively fun and satisfying the way they let you mess with enemies, distract and flank them even after you get spotted, not like other fps like COD and even the main campaign in FC3 allowed less of it, it's better with that in Blood Dragon.
I didn't think people would be so upset about mp, Enemy Territory wasn't the Wolfenstein legacy, it was quite the stand alone title almost merely using the license and little else beyond the WWII theme, while its developers have made other ET style games since with little success, I dunno why you'd think these guys can do better. I'd try a new ET from Splash if they seemed to get around previous issues, Quake Wars was competent but ultimately not for most people but a mix of that with the parkour from their other game, improved gunplay and some parts of COD could be both good and successful, maybe.
Edit: wait, I actually forgot it had multiplayer before Enemy Territory since that's the one everyone loved, there are people who want the base multiplayer as it was before that free stand alone title? 100% news to me.
