Although disappointed, I am not surprised. I doubt there is anyone producing games for Sega with ties to the original series. The current development teams will take the series in whichever direction they see fit. If they think this style will be more commercially successful than a "retro" RPG then that's what they'll produce.
I will admit, this image looks nice:
..but I'm not sold at all on what appears to be the main character:
Nintendo has been wise enough to keep Shigeru Miyamoto in a prominent position so while Mario & Zelda games evolve they stay true to the classic series. With Rieko Kodama out of Sega you can see how the Sonic the Hedgehog and Phantasy Star franchises have devolved.
Despite all this negativity.. I'll probably buy this when it comes out in the US.
