I read this earlier this week, pretty wild.  Lots of upset folks at bigbluelounge.com.  They just released GS4 a little while ago too.

Yeah, that seems to be the kicker. Release Giga4, collect income from upgrades, then pull the plug a couple months later with no more support starting in January. Yikes!
