This type of thing comes up every year.... ever since they stopped production on the CRX. The design always changes, of course.
If they built a new CRX, and kept it true the idea of the old CRX (small, agile, quick, lightweight, affordable two-seat fastback), I'd be there in a minute. I'd sell and borrow whatever I could to own one.
If they do come out with a new CRX, it's looks are going to be based off the current Civic line, just like the old CRXs were. Honeslty I don't think that picture is all that bad looking. Hood needs to be a little longer. And it looks like it has 15" rims in the front and 12" in the rear (artist needs to work on perspective a bit more), but overall it's not that bad.
Actually the pic is pretty good, keeping in mind it's an artist rendition. A current gen CRX would probably have a front similar to the Civic Si, a hatch shaped similar to the Volkswagen Corrado (a little more modern looking that the 2nd gen CRX hatch, but still in the same basic fastback shape). For taillights... who knows... maybe RSX style.
I don't think they'll ever bring back the CRX. If they do, however, it wont look like the old CRXs. It'll have the same basic shape, but a new car has to look like a new car.
