Here's my source for Castlevania Lords of Shadow Mirror of Fate:

Ill try to look for sources of other games, I think I start with Kingdom Hearts since I also remember that one as vividly.

He also said in an interview around the same time

"When nudged on the possibility of the HD build releasing in full one day, Cox added, “Absolutely, yeah. We would consider it. We want as many people to play it as possible. Obviously we have an exclusivity deal with Nintendo right now though and they’ve been very supportive of the product.”"

Certainly seems like their motivation extends beyond their love of 3D.  Also 6 months after this they announced it was coming to PS3 and 360.

But it was going to be on the Vita instead of the 3DS. And it's Koonami who decided to make it exclusive , and then they later change their minds since they had originally did it in 1080p to make it look even more better as a 3DS exclusive, and the thought was really about wanting to reach as many people as possible with what they consider to be a classic-like Castlevania game.
