Part of me isn't surprised if it IS the "real thing". After all, DC kept Superman dead for about a year (give or take) back in the 90's, and naturally Cap's Death has been compared to that other iconic thing.
Plus, NO ONE believes Cap is dead. It doesn't matter whether Logan says it, or the Watcher, or an army of Celestials, because everyone outside of comics is counting the days until Cap returns. It's the nature of the biz. The only way anyone would truly believe that Cap is dead will be if it is 2012, CAPTAIN AMERICA and THE AVENGERS movies have been made or being made with the Steven Rogers incarnation and Winter Soldier (or Sam Wilson or someone else, hopefully not Frank Castle) has been cemented as Cap for at least 3 years in Real Time, then and only then might some fans start to go, "maybe Steve is really gone". And even then, hey, Osborn came back after some 20 years. Bucky after 40. And so on.
Of course, this disbelief about Cap's death, no matter how many times Brubaker has his body autopsied, works to Marvel's advantage for promotions. Plus, it is no secret that Cap's death has been a burst of sales for him. The sales of his ongoing have doubled or tripled since. The FALLEN SON mini-series about perpetual angst also sold incredibly well, stemming the gap between CW and WWH. Death has skyrocketed Cap above and beyond where he used to be in sales, so it's no secret why Marvel would be evoking it for a Ross series.
Genuinely speaking, even though I haven't read Bru's Cap yet, I don't believe this is a genuine resurrection (or a time-displaced one, as was with the horrible misfire that was Mar-Vell). But business wise, it doesn't go against character for Marvel to use distortions and outright lies to sell something. That is usually the heart of marketting. They know fans are counting the days until a resurrection, and they will milk that for all the fans are worth.
