Is the National Sevens on the move?

A curious notice was published yesterday by RFUW. It confirms the date of the National Sevens... but not the venue:

"The RFUW National 7’s will go ahead in the same format as last year on the same weekend, 23rd and 24th May (as detailed in the calendar), venue details are just being finalised and as soon as they are we will email all club contacts with the relevant details and the application form."

You'd have thought that the venue for the tournament would have been agreed months ago - even last year, if it was staying at the same place - so why is it only being finalised now?

Or am I reading too much into this?
