Do Sony's new SLT cameras have DSLR image quality?

I'm looking into buying my first DSLR, or rather looking to step into semi-pro photography. Having browsed the market offerings my main contenders are the Nikon D90 (the D7000 seems overpriced for its specs), the Nikon D5100 (as a more budget-savvy option to the D90), the Canon 550D (for its reasonable price and overall performance) and the new SLTs from Sony (the a33 and a55).
The SLTs pack a lot of punch, especially the a55 with its 10fps shooting speed, but do they actually produce DSLR quality images? Of course, my question is applicable only if we take out of the equation the quality of lens used, so please try to answer with this in mind. Video performance is not important for me.
So, are the SLTs worth it, or am I better off going for the classical reflex system?

The SLT… Well, yes they can produce quality images.

PErsonally I fail to see the point. OK, you got 10fps to impress your friends with. You also got an electronic viewfinder that guzzles power (about 300 pics on battery charge) and you got a far worse lens and flash lineup than Canon or Nikon have.

I got a nikon that does 6fps. I don't think I've ever had a situation where that was not enough. In fact most high speed situations I'm the limiting factor, not my camera.

The semi-reflective mirror probably gives it a significant advantage for video, because it can use the phase detect focus sensors to maintain continuous autofocus. Other live view DSLR's, to do video autofocus at all, have to periodically sample the focus from the sensor they are using to record, using sluggish contrast detect.
Other than that, quality should be pretty close to competing DSLR's. I would guess that in low light the Sony could be at a slight disadvantage. Some of the light that would have reached the sensor gets lost to the semi-refective mirror, and because the mirror does not send as much light to the viewfinder, the view may look dimmer than other DSLR's.

The SLT bodies use the same DSLR sensors as the rest of the Sony (and Nikon, Pentax, and Samsung) DSLR's. The only difference is the fixed mirror.

They are as capable as you are, just like all the other cameras you mention. You can get high quality glass, just like you can for the others, and it costs just as much from Sony as it does from Canon or Nikon.

I, personally, don't care for the SLT bodies, but not because of image quality. I just don't like little bitty cameras. I don't like the Canon Rebel bodies either, for the same reason. The ergonomics are awful, for me.
