Allow me to weigh in a bit on the manual topic, as I am indeed responsible for the packaging in Canada.
In the case of G70, while I'd like to have a manual with the 3.3T Sport and have requested it on many occasions, it simply hasn't been in the cards. Developing an all-new vehicle platform is incredibly expensive, particularly for a newer luxury brand like Genesis where sales volume (and thus program amortization) will be necessarily slower. This is understood - it's the cost of breaking into the market. However, it also means that any new development projects need to be carefully analyzed.
In this instance, it's a case of "we're lucky to have the manual on the 2.0T, because otherwise we wouldn't have it at all." None of our existing manual gearboxes are compatible with the newer-generation Lambda 3.3L engine, but one was compatible with the Theta-series 2.0L engine. The costs of developing a new gearbox to work with the 3.3T engine are simply prohibitive considering the extremely low take rate for such a configuration. This applies even more so in Canada, as the manual is paired with RWD. Designing one to go with AWD adds yet another layer of extremely expensive development work. On top of all of this work, every new powertrain combo requires extensive testing, certification, QA assessment, etc. Finally, it's not as simple as going to an outside vendor - all our gearboxes are developed in-house, with the platforms and powertrains built accordingly. Not only would an outside gearbox (i.e. Tremec, Getrag, etc.) require substantial development to fit into a Genesis vehicle, but I would also suspect the per-unit costs would be ugly as we have no other relationship with such vendors (i.e. no economies of scale or volume agreement).
Rest assured that we'll keep asking and advocating for the manual as a brand-builder that helps draw in enthusiast buyers (read: product evangelists who can advocate among their peer groups). That said, I think there's a fundamental misunderstanding among many about how easy it is to add an entirely new powertrain configuration.
For what it's worth, we're not having any issues moving the top-spec 3.3T Sport AWD in automatic form - this one single trim (of 6) represents >55% of our total sales!
Happy to answer any other questions.
