I too would appreciate the next beta before too long. There are plenty of awesome things about iOS 8 beta 1, but a lot of bugs too (as everyone would expect). I'd downgrade but for the fact I can't restore iCloud backups from iOS 8.
I think too many people are holding on for it coming out tonight - I'm personally not so sure. As many have already said, Apple are really focusing on teaming OS X and iOS together and that leads me to believe new beta versions will go out together. I'm thinking it's looking more likely the end of this week - if not early next week to be honest. If it goes out tonight, awesome, but I'm not convinced.
I'll be happy once the stupid settings bug is fixed (crashes when you open Settings). I'd also like to see the continuity features working a little better - particularly phone calls. As yet I haven't been able to make or receive a phone call successfully on the Mac (it'll ring but audio never seems to be transmitted). That will be awesome when it is working. SMS messages work fine.
We'll wait and see what happens. If it comes out anytime it's likely to be 1pm EST (in my case 6pm BST) but, as I said, I wouldn't be surprised if we didn't see another beta until the end of the week.
I could be wrong but I think the second beta of OSX is out already. I thought I heard that... but, like I said, I could be wrong about that.
