I think they are trying to head off a motion to dismiss or suppress for non-compliance with discovery, in effect saying because you did not follow the discovery rules you should not be able to have any sanctions imposed.
Courts usually enjoy considerable discretion over discovery matters and dismissal or suppression of evidence are extreme remedies which, in my experience, are seldom imposed.
My sense is that they will furnish you discovery--of course you must receive it in time to make meaningul use of it. You can always move for any sanction you feel is warranted, including a dismissal or suppression of evidence, and let the judge make a ruling on your motion. Normally, when discovery materials are not timely furnished, the result is that the case ends up being continued to a future date.
