It's not news. Most of us have known since mid-January of an impending increase of 25% from early April.
Mind you, $44.80 (retail price here in Australia with this increase tacked on) is a very, very steep price to pay for a roll of Velvia. I have sufficient stocks for 12 months to keep me going, after which I'll critically evaluate my direction. These significant price increases are not sustainable (two retailers' own words) and I predict retailers will feel the pinch of stocking film that people will now not be inclined to buy on pricing alone.
