fabric bandwidth on A9K-8T/4

The data sheet for the ASR9K-RSP-4G claims 180 gig/slot
fabric. The data sheet for the A9K-8T/4 does not say
what it's fabric bandwidth is. The "/4" in the part
number looks suspiciously like it is 2:1 over subscription.

Does anyone know the fabric bandwidth on that card?
The ASR9K data sheets are horribly lacking.

2:1 oversubscribed, according to the document at:
http://www.cisco.com/en/US/docs/routers/asr9000/hardware/ethernet_line_c
ard/installation/guide/asr9kELCIGinstalling.html

(see the section on the 8-port card)

The card is 2:1 oversub. The asr9k as shipping today is a 40g/slot
platform. Further information would likely be available under nda.
