Lubomir,
The delivery date is actually up to you, the Bulgarian train fans. The first 2 versions will be Romanian and will be available next June. But then, any of the remaining 8 versions, including BDZ, can be produced next. We have no decision yet about which will be the 3rd modell.
That means that if we have a significant interest for the modell, we will go for it earlier. But anyway, all 10 versions will be produced sooner or later. However, if the BUlgarian fans just wait, then the modell might come only in 2012.
