The Bodnar system uses extremely expensive motors, which in reality won't really offer anything over the other DD options, and they are also charging A LOT for their power supply and electronics package and software. There was definitely a good amount of R&D put into the Bodnar systems, but compared to Fanatec (which has much more manufacturing knowledge and resources, better software development, and so on) the Bodnar package looks pretty amateur in comparison. As Thomas mentioned in the video it is wonderful that Bodnar and other companies put these DIY packages together and helped create the DD market. But with Fanatec in the mix the bar gets greatly raised and they will have to adjust their prices and components to be able to compete. There will always be the small niche that wants a more DIY solution and will think it is better because it is DIY though.
I can assure you the amount of R&D that Fanatec has put into their Podium systems is exponentially higher. They are able to charge less even though their R&D costs are likely much higher because they have good partnerships and can manufacture these at a much larger scale.
