I agree with Cy-Kill. This article basically misinterpreted the one at Phone Arena, although Phone Arena's title was a bit misleading as well.
In any case, Opera (in general) has been available on the Android since the beginning, and was one of the first third-party browsers. Not surprising, since their existing Opera Mini browser was already written in Java, and it didn't take much to port it over to Android. Opera Mobile came over a bit later and both browsers were doing quite well. This particular "Opera browser" is a completely different browser based on the new Webkit engine. The article at Phone Arena was basically saying that its finally out of beta and is now in the Market as a proper app.
To be fair to Nicolaas Du Plessis, for new users it can be a bit confusing with three different "Opera" browsers on the market all made by the same company, all with a similar interface but different engines underneath.
My guess is that after a few releases of the new "Opera browser", they will retire the "Opera Mobile" and "Opera Mini" versions, seeing as how they essentially combined the features of both. Also, I don't think Adobe Flash support is a big concern for them, since Adobe have officially quit the mobile space, so they won't be wasting any resources on it.
It's time for people to move on - leave behind the websites and browsers that still rely on Flash. Unless we users don't move on, web admins will be sitting on their arses laughing all the way to the e-bank while watching their users suffer due to the piece of shit Flash that is flash.
