Hi George,
Both of these mean the same thing:
1) "I will get..."
2) "I will be getting..."
'Getting' is the gerund; the current form of 'to get'. To 'be' implies the doing of something right then, so we use the gerund/current form of 'getting'.
Therefore:
"I will do the laundry later."
"I will be doing the laundry later."
