In UK Consumer Law there is a terminology of Caveat Emptor - this latin phrase translates as "buyer beware". It means that buyers purchase at their own risk and should do their research and ask questions before buying. Sellers are not responsible for problems encountered by buyers after the sale... Xbox GP players should not be deceived by the statement in the TSW5 FAQ that 10% Loyalty discount will expire on launch. In Dovetail Direct JD stated that TSW5 Standard Edition would be available on Game Pass as a Day One Release. Therefore 10% Game Pass discount should apply shortly after and from that point onwards. So in the words of Hitchhiker's Guide To the Galaxy - "Don't Panic"! So prudent advice might be 'try before you buy'! It might also be useful to note that pricing for the Vectron and Pendelino have been announced as separate loco DLC. So no need to purchase the Deluxe Edition just to play either of these locos on your regional route (if you have a preference for one country but not the others). With regard to the WCML South there are apparently Timetable Layers for those that own "The Suffragette Line". Again Game Pass discount should apply to all TSW content in the Xbox Store (although the discount does not apply on release date purchases).
What we said in the Keynote is correct - the Loyalty/Pre-order discount will expire on release day. The Game Pass discount is something completely different, and not something we have control over. It is worth bearing in mind though if you do plan to purchase Add-ons.
