There are currently three models of iPad, you can find a comparison of features here:

The 3rd gen iPad was released in March 2012 while the latest models were all released October/November.
So the 3rd gen iPad is the latest apart from the iPad mini?
No. The 4th Gen is the latest.
Retina with lightning connector.
So the 3rd gen iPad is the latest apart from the iPad mini?
No, the iPad 3rd gen was released in March 2012 and it was superseded by the 4th gen known as the iPad with Retina Display. All the models listed in my link above are the latest models of iPad. Apple have three different models at this time.
That is the latest 10" iPad.
Apple have made it confusing with the constant name changes this year!
Yes, that is how they refer to it on the refurbished store.
Apple have discontinued the 3rd gen iPad so it should be available for sale in any shops.
So the 3rd gen was called the new ipad and now the 4th gen is now called the new ipad? (argos is saying that)
I can't comment on what Argos is saying but the link you posted was for the 4th gen iPad. The major differences between the 3rd and 4th gen iPads are the processor and charging port. The 4th gen has the A6X processor and a lightning port. You can use that to confirm you are getting the latest iPad.
thanks, I'll just look for the A6X chip on the spec on the box
