Funny seeing the media coverage of the iOS version of this where they don't mention the Android version at all. This is why we still have the "Waaaahh Android doesn't have any games" turds still.
I think you can look to a couple of reasons for this.
For starters, Konami didn't put out any pre-release info on either game, they just sort of "appeared" (obviously to promote the movie). Which itself is strange, but not highly unusual.
As for the coverage, you can attribute that to the fact that there is generally more actual consideration of app release coverage in the iPhone scene then there is in the Android scene, sadly. When something of note pops up, it will get interest on one of their (iPhone) dedicated forums immediately and spread from there like wildfire, ensuring some front-page coverage as well, discussion on podcasts, posts on twitter and facebook, etc. Android sites just generally do not care enough about app releases to be so on the ball quite as much, sadly - and this is one of the big issues that holds the Android scene back from attracting more developers to the platform.
I have complained about this same issue in a couple of different threads already, and so I am starting to gain some "broken record" status I am sure - but if that's what it will take to start effecting some change in this scene, so be it.
Case in point - in the iPhone's number-one app-discussion forum, TouchArcade, they have a thread 160 posts long talking about their version of this same game already (released same time as Android). In this thread right here, this is the 4th post after nearly the same amount of time. This is supposed to be one of the biggest forums for game discussion in the Android scene - let's get busy and start some activity
