Hasbro's main problem is that they will Chock these out as fast as they can sell. Wave 4 was released a whole month ahead of time I believe so as to more than likely solidify the fan base. They will start to finally slow down I'm sure to every other month a wave or so.
And yes you guys are correct that Electro is #25. The price for these things are rough, but if they can manage to step the waves far enough apart I won't mind. They already have set a standard number of new figures per wave it seems as well. 5 New figures with like 2 running change variants.
Right now I'm only missing Gray Hulk, as he was like the first Wave 2 figure to sell out I guess. Hopefully I will be able to find one in wave 5 assortments. It took me a while, but I was able to scrounge up the entire first wave, I probably had to buy them at about 8 different stores. Mostly K-Marts had wave 1 in stock, and NO walmart had any Wave 1 figs left except Spiderman and Black Panther. In fact I have yet to see any K-mart stores in my area get any stock of any later waves in at all. Target was the best place for me to find wave 2 and 3 figures, as they keep their stock up pretty well, and most scalpers and collectors hit the sure thing Wal-mart stores first. Plus Target is cheaper! I'm having fun with this series right now for sure, but one thing that I wish would have been included, especially at the price range, would have been some display stands for each figure. It would have really hit over well with Gi-Joe collectors I think. Plus they are kind of hard to stand sometimes, mostly when posed.
As for the Nick Fury...I was so upset when they announced how you had to get it..what ever happened to the old school way of sending in a envelope full of UPC codes and $4.99 for shipping?

I absolutely refuse to accept the ridiculous method that Hasbro and Marvel chose, and I hope not many others do as well, cause I want Hasbro to buckle and make these things publicly available. In fact Hasbro released Fury as a Toys'R'Us exclusive in Singapore at the regular price according to reports...and the Singapore guys who keep selling them on eBay at Super high prices. So either way we are screwed into paying $30 dollars or more for 1 figure, as I'm not paying for comics I can't keep. I have the Library for that, and they have a very adequate bound volume section for graphic novels.
Also I hear there will be a short window of opportunity to obtain the SDCC exclusives at a reasonable price on Hasbrotoyshop.com before or after the Comic Con I think...and hope. Cause I'm not paying those stupid eBay prices on those either. The only one that I really really would want is the Namor anyways, as the Torch, Caps, and Redskull are all retools or repaints of other figures.
But I do like the repaints the line has offered so far. I'm very fond of my Spiderman repaint with the darker reds and blues, and the White gloved Torch is cool as well.
I have very few complaints, and most of those are with the larger figures like the Hulks and Thing. They really need to improve the leg articulation on them. Other than that, there is very little issue. Most have very tight joints, great accessories and awesome paint jobs. Some Scale issues with some characters should be worked out for sure, and Hasbro shouldn't be so stingy, and bring in some new body types. When you think about it your buying a bunch of the same figure with different head sculpts.
