LG had some interesting things to say, at least according to 'What Hi-Fi?'
First, we get more confirmation of a Europe-first launch, where LG says they'll have their 3.8" device based on the Optimus-line (previously seen to be running Android, looky here) ready to go, ahead of Samsung and HTC. This device will presumably be lacking a hard-keyboard.
The next bit is that in the U.S., we'll be getting the version with the keyboard, like above (Panther/GW910), in November. We're guessing AT&T for that one, but wouldn't mind a Sprint model to kick around.
Finally, LG is either trying to make Microsoft look good or they really believe in Windows Phone 7, as they supposedly told Korean reporters that
... it expects WP7 to outperform the two rival smartphone operating systems
The rivals being of course Android and the iPhone (don't you love how Blackberry is not even mentioned anymore?). Sounds good to us.
