The newest ones seem to be a play off Good Guy Greg. Basically Good Guy "Insert Company Here" doesn't sue for copyright infringement for having a pioneering idea (a play off the recent Apple vs. Samsung lawsuit).
Also not really a meme but the hipster thing with text is boring for me, more of just a shot at modern teenagers. There also seems to be a new trend of taking a photo from decades/years ago and getting the same family members/people and taking a recent photo with the same people in it from the same position/location.
Also, it appears the McKayla is not impressed meme seems to have died down now.
