I believe that was referring to oversampling
The Axe-FX uses higher sampling rates (oversampling) during the processing stages. This is how it avoids aliasing when non-linearities are applied. But the sampling rate of the audio that is sent to the DAC is the same as the sampling rate coming out of the SPDIF output: 48khz. In other words, it goes from 48khz (ADC) -> higher sampling rate -> 48khz (DAC).
So just because these higher sampling rates are used for the processing stages doesn't mean it would be trivial to send a higher rate to the SPDIF output. The 48khz signal would need to be sample rate converted (SRC) at the output stage by a hardware SRC chip and Cliff's whole point is that software SRC's provide better quality than what is available with hardware SRC's.

I'm not buying that. Oversampling is usually applied at the AD/DA stage not during processing. Whatever bandwidth is gained when the source is sampled is filtered down to 24kHz (48kHz sample rate) at the input and not changed except maybe during the DA conversion. I'd bet the 24bit word length is increased to 32 or maybe 64 bits for processing. Unnecessarily increasing sample rate (especially for guitar signals) will cost big processing efficiency. I recall Cliff saying other processors employ SRC to 'offer' higher sample rate outputs but the processing is not really occurring at that rate. This SRC process is usually done on the cheap and most likely will add noise or artifacts anyway.
If you want to record your AxeFX at 96kHz, knock your self out!

Adam is completely correct.
Will there be tools available to capture/create IR's and convert I-Version IR's into II-Version ones (or inbuilt into AxeEdit) ?
1) Will there be tools available to capture/create IR's (or inbuilt into AxeEdit) ?
I know if I have the wav file then I can create II-Verion IR's with the tool from 1) - but sometimes I have only the I-Version Files:
2a) Can the old I-Version IR's be loaded into the II?
2b) Will there be tools available to convert I-Version IR's into II-Version ones ?
Eventually there should be. I already sent the file format to AlbertA. I would imagine he'll have a converter soon.
I have a converter that I use but it's coded in Matlab and I don't have the compiler in my latest version.
Is the latency one would experience while using the intelligent pitch shifter be less or equal on the AFII over the original? If so how much?
If you press up, up, down, down, left, right, left, right, A, B, Start then what happens?
