Yes, and also MP will be on Beta MP servers.
It is a first Beta build, so there will be some stuff missing and not optimized in this first iPad Beta build, we also just add a small group of first testers because of this, some testers we hope can see the light at the end of the tunnel together with us.
The AI is not completely replaced and rewritten yet, so turns are still pretty slow (the AI will be completely replaced and rewritten upon release), some PC features are not completely replaced yet, some UI is still from the PC (new updated iPad UI is in the making, but still a bit unstable, so we left it out from this first Beta build), intro movies are disabled, etc... but outside these known issues, we are ready for some testing.
We will add more and more Beta testers gradually once we get closer to Gold. So we hope the first chosen Beta testers are capable of investing some time into the game even with the issues that are known and will be sorted during the next weeks/months of beta-testing.
