Litecoin's blocksize will last us a few more years. If we do decide to change it, we likely won't run into the same political nightmare that Bitcoin is dealing with today. This is because members the Litecoin development team have very similar vision for the future of Litecoin.
The current direction that the Litecoin development team is thinking about is to create a fee marketplace. This, in our opinion, is a better approach to the blocksize debate than to recklessly increasing the max blocksize without full understanding of the consequences.
