Variations on sentence-ending 「〜だと!?」 (used when repeating something in surprise)


In [a recent
question](https://japanese.stackexchange.com/questions/15057/usage-
correctness-of-%E3%81%A0%E3%81%A8-after-verbs), we talked about using
sentence-ending 〜だと after a verb, quoting something you found surprising. The
example given in the linked question is as follows:

> Ａ「なんでもします！」  
>  Ｂ「なんでもする **だと!?** 」

I'm curious what variations だと can take with this usage. I can think of four,
substituting です for だ and substituting って for と:

  * だと
  * だって
  * ですと
  * ですって

Which of these variations are possible with this usage? Did I leave any
variations out?

(Unfortunately, I'm not sure where to look this up. For some reason,
dictionaries don't seem to list だと, even though its usage seems to be
different from a simple combination of だ and と.)




You can add the standalone "～だ!?" or "～だぁ!?" to the list. It's even rougher
than "～だと!?", and it's used almost exclusively in fiction.

> 何でもするだぁ!?

"～だと!?", "～だって!?", and "～ですって!?" are very common, at least in fiction. "～ですと
!?" exists but it's rather rare and sounds a bit comical to me.
