"...probably next year Iran will have the nuclear bomb??"
Iran is having technical issues with maintaining it's centrifuge cascades that will impede their progress. Next year is a POSSIBILITY but, for present, the amount of material that they've been able to accumulate is minute. There are related technical issues that remain unclear such as delivery and warhead miniturization.
There is, however, clear intent to pursue such and time appears the only factor that stands in the way of them accomplishing their end goals.
Here is a nice summary of Iran's nuclear program as researched by the New York Times-

The brief time-line of events this year is followed by an extensive analysis which provides a solid overview.
Thanks.
