No idea if this has been hyped all to hell or not, but being a 2 part 48 page comic is great for people like me, who have stopped collecting single books (Honestly, it comes down to weight. I decided I wasn't going to move more than one box the last time we moved, and sold/gave most of my collection away to a friend.) One of the few comics I did keep is the last time Gaiman wrote Batman (With a really cute cameo by John Constantine) so, I will likely ask my brother to go pick this up for me. Not sure if this plays off of the Morrison stuff or not, but it looks fun.
My big issue with the Red Hulk is that everybody immediately thought it was Ross, and Loeb et. all were like, "No, no, no, it's somebody else, look - Ross is dead." A good story is good even if the readers figure out the ending ahead of time.
