Christian Svensson, Corporate Officer/Senior Vice-President of Capcom recently posted on the Capcom Unity forums confirming that Europe and North America will both receive a demo for Resident Evil Revelations on Nintendo 3DS.
A RE: Revelations demo for NA and Europe is coming.In the case of NA, we're awaiting our date confirmation and code approval from NOA (we have a tentative from them, but I'll have to keep you in suspense).
When we have something more concrete to share, you won't be able to miss it on the Capcom-Unity blog.
With the game releasing in Europe on 27th January, hopefully we can expect it with the next couple of weeks.
