Perhaps the critical reception,
but the sales were very lacking.
I understand the need to try and promote the idea that Revelations sales are disappointing to poor but pointing to the fact that it didn't break 100k in the states during its launch month doesn't prove much. The game sold very well in Japan and debuted at number one in the UK.
Great games, belonging to popular IP's, have constantly shown to have the propensity to sell very well over a longer period of time on Nintendo platforms, as opposed to having mostly front loaded sales. Resident Evil in particular.
I still remember when sales age veterans were very quick to label Mario Kart DS a disappointment based on its first week sales in Japan. Resident Evil isn't Mario Kart but quality installments, of the franchise, have already proven to have a very strong fan base on Nintendo platforms.
Every example of a successful RE game, on Nintendo platforms, has them accumulating the majority of their sales from having very long legs.
Each time those games sales numbers were called disappointing by sales agers just from looking at the launch numbers.
Each time, six or so months later, Capcom would then release a sales report saying the games had sold or shipped enough to make them very successful, having sold several multiples more than their launch numbers. My memory is kind of fuzzy about how well RE4wii/REUC did in the long run, compared to their launches, though I am pretty sure this was indeed the case.
I think we will see a similar situation with Revelations with phase one already complete.
