BPhil admit here! Heard back from Exeter College on March 23rd - three weeks after the offer. It was my preferred college and also the one I'm currently at, so the fact that I'm a known face might have sped up the decision perhaps. Haven't heard anything about funding myself, though neither have I seen other BPhil offer holders either here or at TSR mention any, so I suppose there is a chance. The e-mail said we'd hear by 12 April. Although of course chances were slim to begin with.
There's a page here that lists what BPhil graduates have gone on to do. I've done some calculations as I've got nothing better to do. The first percentage is how many of the BPhil graduates overall went on to do the DPhil, the second how many of the BPhil graduates who stayed in Philosophy went on to do the DPhil:
2016: 28% / 42%
2015: 20% / 33%
2014: 25% / 40%
2013: 35% / 67%
Obviously, some people might get offers but choose to go elsewhere. I couldn't find about funding unfortunately.
