But Dx10 will be released 12-18 months from now. So I guess it´s not impossible that MS will release a Dx version they call Dx9.1 sometime in the next 18 months.
I guess the next major Dx will be released with Longhorn. So when late betas and RC:s of longhorn are released people might be able to try the new Dx. That could be interesting.
Slight OT, but this 'Next' branding seems to getting stuck to a number of upcoming MS products. I hope they don't brand Longhorn as Windows Next. Apple would be livid.
