Don't hold off on buying a DVD-recorder because of rumors about Blu-ray recorders being available soon. I've never heard about any US or European release dates mentioned by any company developing Blu-ray disc recorders yet. The predictions made in news articles are to my knowledge just speculation by the writers. If I were to come across a direct quote by a reliable source I would definitely post about it on the site. DVD-recorders have come down in price a lot lately and you can get a fast DVD-recorder at a very affordable price. I don't think you can go wrong with buying a DVD-recorder as both the recorder and the media is cheap.
P.S. I wouldn't worry about such a decision until either of the products at least has been released
