Madonna is an old star now. She doesn't interest the net anymore as before. She sold many tickets for this tour but really could be in front of empty seats.
She has to find something that could interest the net. Here with her hospitalization she just has to hope not to be in front of empty venues. Sold tickets but seats not occupied.
Yes it is very strange not to see something about the tour on the net. Yes Britney on her show in Las Vegas. That's all.
