Learn English – The real tense of “I’m going to be talking about”

If you say or imply 'A year from now', the better choice is: 'I will definitely be living away from the shop'. This is because the future continuous is used to refer to an action or state that began before some point in the future and will likely continue after that point.

You can say 'A year from now I will definitely leave the shop and go live somewhere else', but in this case 'a year from now' implies 'on one particular day a year from now' rather than an indefinite period of time surrounding that day.

If the subject of your sentence is "I", then Barrie's brief explanation correctly summarizes the essential difference between going to and will. Example:

• I'm going to go shopping after work today.

means that you have already planned what to do later.

• What are you doing after work today? - Haven't thought about it. Maybe I 'll go shopping.

indicates a plan made at the time of speaking.

Of course, you are not always the subject when talking about the future, and the focus may be on predictions rather than plans. In such cases there is no simple rule to follow. For example:

• She's going to have baby (not: She will have a baby)

and

• The baby will be her second child (questionable: The baby is going to be her second child)

Talking about the future is one of the most difficult aspects of English grammar for non-native speakers, and includes many more than the two forms discussed here. I recommend investing in a good reference such as Swan's Practical English Usage, and asking specific questions here on this site if you are not sure which form you need in any given context.
