The New Backpack: in-game character editing?

Well, as some of you may have noticed, ROBLOX have recently updated the backpack to a bigger one that fits more, and I think this may have something to do with in-game character changing.
Here is a picture of the new backpack:

It has been enlarged.... what could this mean?

Well. There is tons of things it could mean, but there is one main reason.. Remember that while ago they prototyped the in-game character changing. Well, they had the same backpack, pretty sure! Here is a pic:

This is a very suspicious thing ROBLOX have done, but with a little research, I have found this conclusion. There is no other conclusion as to why the backpack looks exactly the same to the old prototyped one. There can't be another reason, look at them! They're excactly the same! Although the new backpack only has one option - gear. It could be leading to the next tab. And I personally don't think wardrobe will be the last tab. I think they'll keep the backpack for a while. And the wardrobe. But probably ROBLOX will do one more tab, something to do with the character- perhaps in game private messages.
