D7000 Owners: What camera would you have for when you can't take your DSLR?

I'm interested in the outcome here?  I have D70 and D90 plus all the extras and used to travel with a CoolPix 5700 when I need to be light.  I found the biggest issue I had with the Coolpix is 'no image' in the viewfinder when shooting in 'burst' mode.  Hopeless for a moving target and I like to shoot action and sports.  My question then is if I purchase one of the cameras being suggested here can you now see whats happening in the viewfinder when rattling out at the max FPS.  Anyone who has a DSLR knows what I'm talking about.  I like the idea of mirrorless providing I can see whats going on.  When you research in the 'camera review' section of dpreview they never mention this feature????
