I noticed that, too. I wish they'd go back to those mid-week celebrations on the day itself - putting them all on Sunday essentially makes them disappear, which of course is probably what the folks behind this really wanted, anyway.
I think it's also a very important witness for people to see Catholics celebrating feast days on their own calendar. Having a public Corpus Christi procession on a week day makes an impact - heck, having alternate side of the street parking suspended in NYC so that Catholics could go to Mass on weekday Holy Days of Obligation also made an impact. It made the Church and its liturgical activities noticeable, rather than making it look as if we do everything possible to accomodate ourselves to secular schedules because our own practices really aren't that important after all.
Amen. Not to mention the Holy Eucharist was instituted on Holy Thursday, as well as the connection to ordaining priests to the sacred priesthood.
I remember Someone saying something about "a sign of contradiction" ...
