Yes. But only in specific circumstances.
In other words, I will keep buying my favourite series in ebook (so that I can read the next book the moment it's out) as well as hardback (which takes two weeks from release to get to me but looks oh so much nicer in my shelf than the ebooks
) and paperback (different cover art; some of the paperbacks have had extra short stories in the end).
I will also buy the occasional paper book when it's a book I think I
really want but isn't available as ebook, or the occasional paper book when there is no legal ebook but I've acquired the ebook by other means (and consider it a "keeper", not a "library trial"). (And in all of the above-mentioned cases, I buy new if new is available to buy, both because new is generally cheaper with BookDepository's free shipping than having to chase down a used copy and pay considerable shipping charges, and because I prefer the author & publisher to get paid.)
And then I imagine there will be the occasional, extremely rare case where I know I want the book but not necessarily the moment it's released and the ebook is essentially as expensive as the hardback - case in point, after some deliberation, I've pre-ordered the hardback of JK Rowling's upcoming novel for ~15 € instead of the ebook for $20. If the ebook had been considerably cheaper, I might have opted for that, but I have a feeling this is one of those cases I'll want the physical book in my shelf anyway.
But in general, I expect my paper/ebook purchase/read ratio stay around where it's been since I got my Kindle ... I don't think I read more than five paper books last year, compared to over 100 ebooks, and this year I've bought or pre-ordered 107 ebooks vs six paper books so far and I've yet to read a single paper book, as opposed to 62 ebooks since 1 January.
