@ Vengeance: you're still pissed at Kishimoto retconning his timeline? Tobi is Obito, obviously the timeline is no longer an issue in Kishimoto's mind.
1) It wasn't this chapter that made the retcon, it was the previous one, so don't place blame where it doesn't belong.
2) Hashirama's personality wasn't this chapter's doing, it was already presented to us in chapter 619. And Kishimoto made it pretty clear he was going to mirror Naruto in Hashirama, so getting flustered because it actually happened it's kind of naive.
3) Izuna was Madara's younger brother, so it's unknown if he was a shinobi by this time. Also, I think we'll see Izuna pretty soon considering the sibling line, explaining why Madara was so attached to his brother.
This chapter is flawed, certainly, but that doesn't make it a bad chapter. On the contrary, it has so many goodies it's bound to be good. Considering the manga we're reading, I dare say it's the best chapter we had since June.
