I currently work under Tig on Ol' West and Kingdoms iPhone and I can confirm both are still undergoing continuous development. Ol' West is, I quote from Tig; 'on the backburner right now but not -dead-'. In other words, not much is happening at this point in time.
Kingdoms iPhone has slightly more activity than Ol' West recently and was been primarily been worked on only one or two months ago
and was really starting to take shape, however, a lot of the staff, myself included have been busy as of late and are unable to commit ourselves fully to the project.
So, basically, the Ol' West and Kingdoms iPhone projects are paused for the time being but there's a ****load of content and potential there waiting to be continued
-Zodiac iPhone has recently returned as stated in previous posts. However, it seems like development there is slow going alike many other servers as there is rarely a playercount online.
-Delteria seems like it's been under heavy development.
-Zone iPhone apparently is going to be apart of Era iPhone.
-N-Pulse is looking to start an iPhone server in the coming months so look out for that.
-Stroseria is awaiting approval from Stefan and co.
Hope this cleared some things up
