And it seems there is no answer about the Darkcoin logo into the BBL wallet tray icon ?

Read between the lines, this is DRK 2.0! just w8!

Exactly, it's DRK 2.0 in at least 1 aspect:
With an even faster instamine 1.8m in 18 hours.
The next 1,8m coins at current block reward (25) will take 125 days.
Interpretation of these facts is up to every individual of course : )
That's not true. It took less than 8 hours for over 1.6M coins to be mined with Darkcoin, which uses the same block reward structure and started at 500 coins per block as well. All without even a Windows wallet available for days.

1,6m in 8 hours or 1,8m in 18 hours... meh
But it's true that DRK had only linux wallets available at first, those devs are loaded big time with only a small influx of DRK the inflation is minimal.
I hope that the BBL devs are extra motivated to make this coin awesome, who knows. I do think that devs should be rewarded if thay deliver, so who knows...
