Yup, where I work (Blockbuster) my store will be carrying Blu-ray by the end of March, while some of the bigger Blockbusters in my area already have them. Last night I went and did I think of the BluRay website to get "certified in Blu-ray technology."
One thing I really dislike right now about my local Blockbusters is they carry very few Blu-Ray movies. I think they maybe carry a total of 20 for each store. That doesn't give me a whole lot of options to rent, and I don't feel like spending $25 each to buy something I'll watch once a year or less.
