According to this post it will have a compass.

I dont know how reliable this is....
I am going for the moment. It has serveral things going for it IMO. I like the 800mhz proc and it is a samsung proc with grafics accelerations via OpenGL. Also, like you said the slide-out keyboard.
I can say that I have the Hero and the SenseUI is underwhelming at best IMO. I have played with the G1's and the interface is cleaner. Also, 2.0 will relase on the Droid and this will ship with 1.6 (there are conflicting reports on this). Soon enough we will see. The Hero would be nice if it had a keyboard and a faster proc to keep up with SenseUI. But, then it wouldnt be the Hero....
