Letter from DWP about appeal

Just a bit of advice please, I appealed the decision to be put in the WRAG last nov. I got a letter from them today stating that they haven't reversed their decision and the appeal papers have been sent to the tribunal service and they will write and tell me what to do next, does this mean I will get a letter from the tribunal service with a date for the hearing or does it mean they will write and tell me I can't or can't go ahead with it?

Also will my ESA WRAG rate drop to the assessment rate now they have sent the appeal to tribunal or will it stay the same?
Thanks
