A listing for 'Killzone Trilogie' has been spotted on Amazon France.
Price at 60.00 Euros, there's been no confirmation whether the product is legitimate or not. The potential collection is slated for an October release.If the trilogy was to be confirmed, it wouldn't much a surprise to see the original Killzone given a facelift. Sony have supported HD updates over the past couple of years, so it would make sense.
More on this as we get it.
