Yep, consoles is the money maker for all games. Look at a game like Skyrim, one of the top selling games of all time, over 20million in units sold is a huge number. One would think with the added perk of Mods the PC would outsell consoles, not even close. http://www.statisticbrain.com/skyrim-the-elder-scrolls-v-statistics/ 59pct Xbox, 27pct PS3 and dead last is PC with 14pct of sales. We'll see how Witcher 3 fares in the console sales figures, but one things for sure, it'll top PC.
Steam users are cheap - we usually wait for offers.
Honestly, who would buy it on steam when there is drm free gog alternative? Also this is one of the games that deserves to be on a shelf and retail connects to your gog account, not to steam.
