Which size viv are you getting?
I've never used those new vivs so couldn't say for certain if there is enough ventilation. If you get a digital hygrometer and bung it in there, if the humidity gets too high then drilling small holes would be a sensible idea.
Something that I did read about those vivs that you may want to check before getting the animal is the vents. Apparently some people have found the edges to be extremely sharp, sharp enough to do some real damage if a beardy got his toe stuck in there.
