Resident Evil Remaster HD's website recently updated, featuring new screenshots of the theme fans receive if they pre-order the PS4 version. One of these screenshots sported an image for "Biohazard Zero", the Japanese title for Resident Evil Zero.
Following the announcement of Resident Evil Remaster HD, fans began to speculate on possible other games in the series that could use a new coat of paint, and Resident Evil Zero (as well as to a greater extent Resident Evil 2) became a prime candidate. These images could point out that Capcom is well aware and may already be making plans for such, or they could always have just goofed and had some random file on that console's hard drive. The website pulled the image in the blink of an eye, and now shows the same image with the Resident Evil Zero icon removed.
The upcoming Resident Evil HD Remake will be cross-buy compatible (PS4, PS3) to anyone who preorders the game on Sony consoles. The game is now available for pre-order and can be pre-installed so players can start the moment the clock strikes midnight. Resident Evil HD Remaster releases January 20, 2015.
More details may come after the release of Capcom's take on episodic gaming with Resident Evil Revelations 2. Episode one will release February 17, 2015; with episodes two, three, and four releasing February 24th, March 3rd, and March 10th respectively.
