Yes, but we know that for other reasons. For instance, James Sanders' name was misreported everywhere; apparently it's James Vega. ("Sanders" might've been a placeholder name.) It was reported that there would be a seventh class, focused on melee; this is blatantly false and has been directly contradicted by devs. It was reported that Miranda and Jacob won't return in ME3; this is nonsense. Repeatedly, magazines (especially the Official PlayStation Magazine) have been guilty of either misrepresenting or completely falsifying plot details and gameplay mechanics from the previous two games, as well.
In addition, there's loads of stuff that's pure speculation. Ash/Kaidan being Spectres is a guess. Wrex being a temp squadmate instead of a permanent one is a guess. The inclusion of space battles is a guess. All speculation that "RPG elements will be reduced" is a guess with absolutely no support (every single dev comment wrt "RPG elements" has been that they'll be more important, and Hudson and Norman have specifically stated that exploration and roleplaying and a character-driven story are some of the highlights that have been most important in game design going forward). Tali being a squadmate is a guess. The inclusion of more species is a guess. The way powers mesh together is wild mass guessing; it seems like no two magazines have the same idea about how upgrades will be done.
But regardless, I'm pretty sure something can be a spoiler regardless of whether it's true or not.
