1: It is absolutely hilarious to claim that Armenia has super-duper weapons wich it keeps supposedly secret. The S-300 was not there for 7 years, ex-Russian S-300PT's btw, was given recently to Armenia. Armenia, a very poor country on-par with Moldova has no financial capabilities to buy any modern arms, and Russia will never give Armenia any new weapons. And about secrecy, Azerbaijan's MoD does never give any information on procurement of arms, the information you find about Azerbaijan's arms purchases are given from the other side, not Azerbaijan. Just because Armenia don't have any arms market to speak of, and you don't see such kind of news about Armenian arms contracts, does not mean that it keeps it secret. Armenia has no real activity in this field.
2: Azerbaijan has remaining oil-reserves of about 2 billion tonnes, confirmed by BP. Now, tell us how oil is goind to end with oil out-put at 40-50 thousand tonnes a year? The drop in oil production was related to some other issues, the oil-proudction will rise to 55 thousand in 2015, it is higher than previeus highest figure. And it is a well known fact that there are more oil in Caspian Sea, higher figures than Azerbaijan's current proven oil reserves.
