According to Jeux Video, the statement regarding I Am Alive's fate as a downloadable title is not currently confirmed.
Last week, many sites (including 3RM) were reporting that I Am Alive was coming out this year as a downloadable title. This was accompanied by other reports that the game had been through a bit of developmental problems over the last few years.
At least one of those facts has been proven false, or at least unconfirmed. Apparently Jeux Video was joking when it stated that it had been demoted to downloadable status. So, while the development issues might be true, the means by which it will release are still unknown.
