Can't really see a downside to this at the moment. Days of Wonder merged with Asmodee a few months ago and has basically remained independent, and my understanding is FFG will remain an independent publisher under the overarching Asmodee group as well.
It is interesting that they mentioned some FFG titles may transition to other Asmodee groups if they're a better fit there, and likewise, some Asmodee titles may transition to FFG.
I would have to think this gives FFG a much better European base of operations and will result in improvements to organized play for our international Netrunner players, definitely a plus.
For fans of Asmodee titles, it's interesting to note that they announced the first ever Organized Play kits for Seasons last month, complete with playmats, alternate-art cards, and a promo poster for retailers. Makes you wonder if FFG and Asmodee might have already been working together behind the scenes over the past couple of months, maybe?
To further speculate, some thought the primary reason behind Asmodee's acquisition of Days of Wonder was to get their hands on the DoW digital team, which was behind popular apps for Ticket to Ride and Small World. If FFG does not yet have a plan for digital implementations of their LCGs, it is worth noting that they now have access to a strong and experienced team of digital designers.
