Anyone know if/when will open up a developer seed of Lion? I'm a paid developer and I work in IT so I would like to test it as much as possible before we get it for work.
We don't know, but we can presume, it will happen before WWDC if a summer 2011 release is to be trusted. Maybe in January?
Total guess, but I would imagine at the event that is normally held towards the end of January.
