The more I think about this, the less I'm beginning to care! Don't get me wrong I like the Canon products I have but I've pretty much grown tired of waiting for Canon to wake up to the fact I want a good small camera.
Canon cares about what the market wants and what they think they can sell. Frankly, there's nothing wrong with a company deciding not to enter a particular market segment. Maybe Canon is getting it right by waiting for everyone else to get it wrong and see where the market goes. Personally, I don't quite get the interchangeable lens compact segment... it's hot, people are buying them, but is it just a fad? Canon has the size and depth to wait it out.
I'm very close to ditching my Canon SLR gear and picking up a Fuji X100 and maybe eventually a Leica. I don't like that Canon are being so slow to market, they don't impress me with innovation that I care about any more, that will help me take better family photos, videos and studio shots. I want either an affordable, smallish, superfast, 45 point AF FF SLR with a flash built-in, or a small rangefinder style camera.
If you're thinking of ditching your SLR gear for an X100 or Leica then just do it you probably don't need the SLR for what it is best at. Two very different products for different photography. They don't really overlap. Are you suggesting you'll be taking studio shots with an X100? I don't think so.
Affordable, small, and pop-up flash... but also superfast and 45 point AF? Not sure all that goes together... maybe one day, not just yet.
The new Nikon V1 sounds perfect for what you need... get the pink one. Sorry, just kidding about the pink but seriously given what you said you want (other than the studio work) it just about meets your requirements.
