That's what surprised me. The fact that it is a Nintendo game.
It wouldn't have been if it were Sony, where I've already seen pretty much everything.
As Shiroi and Jorge said, I guess it's technically shounen-ai. But no less surprising... and nice

So... I see most of the fans don't like Isaac.
Let's have some fun here

(the fanfiction fangirl in me wakes up again)
What if (just... what if) the 1999 game finally comes out, but the story's epilogue reveals an aging Julius coming out of the closet? He's telling his son and his grandson the truth... he married to continue the Belmont legacy, but he was secretly in love with (insert partner name here).
How would that feel?
Or, on the other hand...
What if, for example, Lords of Shadow would have depicted a flashback scene on which Sypha falls to Carmilla's temptation? (and we guess the rest just by sounds, looking at candles, like in GoW).
