Have you guys all read the Secret Invasion prologue? It's a pretty sneaky way to try to trick us into subscribing to Marvel Digital Comics Unlimited, which, by the way, is totally limited, so I don't know how they get off using Unlimited anywhere in the title. I'm pretty sure that, within the next five or six years, all the major companies will have substantial online archives that we can access for a monthly fee (it might take longer than that, since these major companies move very, very, very slowly). Marvel DCU is a step in that direction, but the lack of complete runs and the crappy interface make it less than appealing right now.
HOWEVER, subscribers get a free 7-page preview of Secret Invasion this week, although I don't know how that works, since I'm not a subscriber and I just read it. Anyway, the prologue is pretty cool, and when I started reading it, I was excited because it's all about S.H.I.E.L.D. and I thought, "wait, is Bendis ballsy enough to tell Secret Invasion from the POV of S.H.I.E.L.D.? Is it a full-on S.H.I.E.L.D. comic?" The prologue is, but when you get to the end, you'll find out that the series probably won't be.
And, thus, I'm going to throw out a major SPOILER right now, although I don't even know if it qualifies as a spoiler since it's in a free preview AND marvel_b0y already leaked it a week ago.
Dum Dum Dugan is a Skrull, and he has been since the day Captain America died. That's right true believers, check your Marvel comics from the past year, and look for all the Dum Dum appearances. That dude has been a Skrull the whole time.
Man, I can't wait until they reveal that Aunt May is one of those sneaky Manhunters.
