Bonus for PC gamers? I'll accept MoF HD, ok?
Most likely... ever since Mirror of Fate HD released for Xbox 360/PS3, Cox has been very quiet on questions regarding the PC release (I even contributed, I got no response). It would be a generous motion since the consoles got the first Lords of Shadow 3 years before the PC version, also received the Castlevania bundle containing LoS, all of the DLC, and MoF HD which itself included the demo for LoS2. I myself would pay for it, but I presume that MoF didn't get that many sales overall and it would at least be played if it were included with LoS2.
Whether it's true or not, I dunno... Konami could also include MoF as a pre-purchase freebie for steam users much how I got XCOM: Enemy Unknown for free for pre-purchasing Bioshock infinite.
