SA are at that weird place in the career of "power/prog" metal band. They were at the point where you have put out a 3-5 successful albums and need to decide what to do next. Many bands in this genre and metal overall just decide to keep doing the same thing over and over (Sabaton, Hammerfall, Dark Tranquility, Amon Amarth). This can have mixed results, with some bands I am willing to tolerate them doing ever so slight variations on their core sound, while most of the time it bores me. Or the band can decide to try to depart. This again can have mixed results, which is true even in the case of SA (I grew to love Unia, but just could never get into Days of Gray). This can particularly be dangerous for a band in the power genre since many fans (a generalization, I know) tend to either be very meat and potatoes, stuck in a previous decade or just plain narrow in their tastes. Well SA decided to change it up again. In some ways they are reigning in the experimentation and prog elements of the last two albums and bringing back some of the more simple catchy elements of the past. Yet, this is still a progression of their sound since they are experimenting with some more straightforward song structures (Shitload of Money) and with different sounds (Cinderblox). Plus you have the truly epic Wildfire parts 2 & 3.
While I would not quite put it up with their classic material, I do like it quite a bit (I have been listening to it a ton since I got it). I am glad to see this band moving forward and trying new things while not abandoning the things that made me love the band in the first place. Is it going to please everyone? probably not, especially those fans that will never get over the fact that they are never going to write Ecliptica again.
