Sort of. The larger companies that own the two brands are merging, but Bud and Miller will continue to be operated separately in the US. I can't imagine that Miller products will disappear completely from Nats Park, just as you've always been able to buy a Bud or a Bud Lite there.
Did they sell Bud at Nats Park last year? I didn't think they did, but since I don't drink it I wouldn't necessarily remember. My understanding is that Miller Lite and MGD are out and Bud and Bud Light are in.
District Brews (or whatever it's called) remains the same.
