Famitsu recently ran an interview with D4 Enterprise's Naoto Suzuki on the current state of Project EGG, and things seem to be going extremely well for them right now: sales of the first couple of EGG Console releases have been great (magnitudes higher than standard PC EGG releases, apparently), and they're pushing to release 2~3 EGG Console games per month, with the idea that some of the bigger licensed games might subsidise releases of more obscure games. They're also in talks for some sort of collaboration with Japan's non-profit Game Preservation Society (gamepres.org) for the specific purpose of figuring out how to reissue games whose copyrights can not be secured or located due to rights holders dying, being impossible to find or identify, etc.
The most interesting statement is that they plan to be more aggressive about expanding EGG overseas, both via EGG Console but also the established PC service, and they're considering widening EGG's scope to include European computer games. I do wonder precisely how they intend to launch Project EGG overseas... they mentioned their recent tie-up with Antstream not too long ago re: MSX, and that they're working through issues/R&D on precisely how much of the current infrastructure can be launched worldwide, so my big fear is that they're going to give up and dump their catalogue onto Antstream or otherwise screw it up with cloud-based nonsense, but I'm getting ahead of myself.
(EGG did attempt international expansion back in the mid/late '00s, in collaboration with a Dutch MSX fan group called WOOMB who intended to not only publish but localise D4's catalogue, but they only got a couple games in before folding; the silver lining was that the initiative lasted just long enough to ensure D4E set up global-friendly payment options on their own service, which have persisted to this day.)
