Interesting article posted by Patrick Selten from dutch multi-platform magazine 'Power Unlimited' dated June 1994. It goes as following:
"In The Netherlands 20.000 CD-i players have been sold up until the end of 1993. Actually we didn't expect that.Perhaps it is because already 130 CD-i titles are available and a CD-i player is much cheaper now than it used to be before. According to Philips around half of the CD-i buyers also buy a FMV cartridge. Kids who got a CD-i player from their parents instead of a Megadrive or SNES need to wait a little longer on titles like The 7th Guest, Microcosm, Creature Shock (by Virgin), Flashback (by US Gold), Rise of the Robots (Mirage), Burn:Cycle or one of the other beautiful titles that we've seen in London last month. It seems like two Mario titles are coming to CD-i (one of which will be called 'Hotel Mario') and also a photo realistic Zelda game.
According to Dave McElhatten (responsible for the CD-i games) Philips will focus a lot more on games the coming years. For example in Florida they're shooting a game with Hulk Hogan, which will be called Thunder in Paradise. This production will cost over 1 million dollar. When I asked John Hawkins (president of Philips CD-i) if he has an answer to the horsepower of 3DO, he told me that the FMV cartridge slot at the back of a CD-i player was not just for a FMV cartridge. Perhaps he meant that you could build in some kind of superchip in your CD-i player so it could process these millions of polygons. We're looking forward to it!"
