The official specs are 240 'cores', and clocks are at 633/1404/1134MHz for GPU, processor and memory respectively. Yawn. GDDR3 of course, no GDDR5 now or until the GT300 cores, the GT200 can't do it, but that is old news. Things are going to suck for NV on a die area board layers, and therefore cost for the rest of the year.
So, what is the sleazy part? Where to begin, where to begin. The first one is that there is no GT275 card or ASIC, in fact, as of CeBIT, the Nvidia partners didn't know it existed, mainly because it didn't. This 'planned' card wasn't planned, and is what you call a reaction. Take a sticker, slap it on an existing card, and blow different fuses.
