The dividend will get declared as Intel Board stated. The analysts are just following standard practices. If you buy INTC today, you can expect at least the 18 cents going forward with reasonable certainty.
BTW, there have been dividends/distributions that have been retracted. The latest one to come to mind is when the Swiss govt told RIG not to pay its distribution due to pending litagion.
All the machines that compute yield, use the ttm actuals and are not forward looking.
