Its taken us this long just get to a She-Hulk, Yellowjacket, Black Knight, Quicksilver(!)...there's lots yet to make.
Oh, I agree, the Marvel Universe as a whole is almost unlimited in character choices. There are a lot of figures I'd still pick up if they were made (Nova, Tigra, Black Bolt and the Inhumans, USAgent, Cloak and Dagger, Tombstone, Chameleon, Spidey's supporting characters, and more that I can't think of off hand), it just seems like some of the waves so far aren't really as solid all around as the ToyBiz ones were - just because of the character selection. It is of course all subjective to what people want and are interested in though. I am really looking forward to Series 2, but for 3 of the 7 figures in the wave. Same with Series 3, if it all pans out, it will likely be another 3 for 7. I'm overjoyed to get those three, but it was more common for me to buy entire waves (or close to it) with previous lineups. This isn't necessarily Hasbro's fault, its just that a lot of the characters have been tapped at this ponit. You are right though, there is many, many years worth of choices of characters to do yet - its just a matter of how/when/if they do them.
