Voodoo Extreme heeft wat info over de 0,25micron TNT:
Although I can't disclose any information on unannounced products, I can say that if you buy a RIVA TNT today, you won't have to worry about obsolence until well through 1999.

Ok, so a tad vague... I fired off an email to nVidia to _attempt_ to get a bit more sauce, in particular, if the "obsolesce" was in reference to the 0.25 coming out or the TNT2 making both the 0.35 and 0.25 obsolete. Here's their reply to my email (and a bit Jason had to say about assuming that nVidia meant late 99):
I am referring to obsoleting the current TNT chip. Jason is wrong in his conclusion about late 99. Must be too much turkey. ;) Seriously, we have a record of delivering products to fit into our customers' schedules. In the case of the PC industry, there are Fall and Spring seasons in which there are opportunities to bundle product. The RIVA TNT was designed to hit the fall season (which it did). The RIVA 128/128ZX was designed to hit the Spring season, which it did. You can draw your conclusion from that.
