Newcastle reached the cup semi-final by easing past London Irish yesterday, but where they will play their opponents Sale remains a mystery.
Twickenham will announce the venues today and last night a double-header at Reading's Madejski Stadium or Headingley remained a possibility.
The Newcastle owner Dave Thompson thinks otherwise and argues that being first out of the hat in Saturday's draw means they are at home on January 6th.
The rule that semi-final grounds must hold 8,000 will not deter him, either, as Newcastle say they have council permission to upgrade their capacity from 7,200.
"We have satisfied the ground criteria the RFU laid down and so we will be playing the tie here. They haven't got the faintest idea what they are doing," said Thompson.
"How can you possibly run a multimillion-pound business when you have no idea where you will play your next fixture?"
Home advantage means a lot to Newcastle. They are a much more virile force in their own backyard as the two meetings with London Irish in the past week have proven.
Newcastle were winged 19-17 on Tuesday in Reading, but yesterday could afford a sterile opening quarter and still finish comfortably on top.
Geography is one explanation; another was the return of Jonny Wilkinson. England's stand-off is known for metronomic goal-kicking and duly landed seven out of eight attempts here, but his piece de resistance was a rare try.
It came in the 49th minute and put Newcastle in the clear. Irish expected the usual three-pointer when Wilkinson walked up after Newcastle were awarded a penalty in front of the posts.
Instead the 21-year-old saw a gaping hole, took a quick tapped penalty and strolled over unimpeded for his second try of the season.
His conversion put the Falcons 23-10 in front and a training-ground gem from Va'aiga Tuigamala three minutes from time rubbed Irish noses in it.
Liam Botham was on the end of robust approach work from Tuigamala in the first half, cancelling out a try from Junior Tonu'u, and, though Justin Bishop touched down in injury-time, Newcastle were beyond concern.
