Also if you're interested in a physical Vita copy, the creative director of the game has given these details on his Twitter:
Details for the RETAIL version of Child of Light on PSVita: 1) Not a Dwl code. 2) Price is 24,99 Euro. 3) Not planned in NA.

Of course, it is Twitter and not officially announced by Ubisoft, but that's pretty exciting! If you're in North America, PS Vita games are usually region free so I'm sure you could find it online once pre-orders are available.
The game is due out July 1st in North America and July 2nd in Europe. I gave Child of Light a 9.6/10 in my recent review which you can read here.
