PB15beta : PBNI and 64 bit support

Hi

I have heard that PBNI won't support 64 bit deployment.

Is it true?

Is there an official statement from SAP of all the unsupported features when building in 64-bit, compared to 32-bits?

What about all pbx's available at the moment in 32-bit ( pbdom, webservices, ...) ?

Thanks

Philip

PS : I think that there should be no difference in functionnalities or behaviour between the 32 or 64 bitness. Otherwise, 64-bit will be useless.
