I have 65 HD DVDs, but there's only ONE on my list for the next six months (which is on order). So far, there just isn't anything worth buying in 2007 (that has been announced). On the other hand, there are 18 BD titles that I'm interested in and count is rising. Unless Fox, Disney, Sony, MGM, etc decide to go neutral soon (which I thought would eventually happen when I bought my HD DVD player -- but now realize it may not), I'll have no other choice but to invest in BD technology as well.
Even if HD DVD comes through with their rumored "300 titles" in 2007, I would still seriously have to consider BD since there are a LOT of movies from Disney, Sony, MGM, Fox (among others) that I'm interested in.
