Followed by "PC gaming is dying, lets focus on consoles!" That'll help.If just those who buy the games to play them using wine would *not* buy unless there is a native binary, this might already help a little. Though the publishers will then probably just say "hey, our sale figures dropped, shame on you pirates!".
id Software, Epic, and Bioware weren't big enough? id has supported Linux for a long time (weren't there Linux ports of the original Doom? and even if it may not be "commercially supported", I'll be surprised if we don't see official native Linux binaries for Rage and Doom4), Epic has supported it since gobbling up what was left of Loki until this UT3 fiasco, and Bioware made at least Neverwinter Nights for Linux (one of the expansions even came with a (broken) Linux installer on-disk), which they were still providing patches for until just last month when they stopped patching the game altogether.Unless maybe a big player like valve makes an offer for Linux and show the other big publishers that there is a big market to conquer things are unlikely to change.
