Hardly.
If they do: It'll be an overweight pig, and will likely not be powered by a K motor. If it is, it'll be an econo motor, and not a k20a2 or anything. It'll be big, and probably not handle very well. It'll look akward, and not carry over ANY of the major styling cues that the crx has to offer, except for a faint glimpse of a flat rear window, which will probably look much like that mercedes or worse, a smaller aztec.
If they don't make it: Most people will continue to say "i told you so", and yell and complain that Honda doesnt make another CRX, but then yell and complain when they DO make the crx, because of all of the above reasons.
Regardless, the only thing it will share is a FAINT resemblance of overall shape, and an overweight and flexible shell, so we're almost better off NOT having it made, because the new one won't reflect much heritage... but if they do make it, it may boost the value and consumer awareness of the 'classic' CRX body.
Now... would i buy it? Well, depends on what motor it includes, what it looks like, and how much it is. If it has a K20, is priced reasonably, and carried over clean, aggressive, and very accurate details, then yes, i would still buy it to compliment my "classic" 8)
