Personally, I believe AEM still has room to grow for at least a couple of years, unless there is a sudden industry downturn.
1) I do believe that AEM's technology has an edge over their competitors. And I think Boon explained it well. To reinforce the point, if Intel really have the technology for the entire HDMT system (ATE market), why does Intel still need to purchase from AEM?
The next question is, is Intel really AEM's customer? The answer lies in AEM corporate presentation dated 20 Jan 2017. We can see that AEM has field support in Oregon (US), Chandler (US), Austin (US), Costa Rica, Chengdu (China), Penang (Malaysia) and Ho Chi Minh (Vietnam). Next, we can check Intel's Manufacturing Factsheet that Intel has similar operations in Oregon (US), Chandler (US), Austin (US), Costa Rica, Chengdu (China), Penang (Malaysia) and Ho Chi Minh (Vietnam). We can also see that majority of AEM's revenue is from US, Malaysia, China, Vietnam and Singapore.
Thus, we can see strong clues that AEM is supporting Intel's operations. The fact that Intel still purchases from AEM shows that AEM's technology is indeed superior. Personally, I read through AEM's patent and logically, it does seems efficient, due to its modularity and "scaleability". Although I am not too sure how easy will it be for their competitors to go around their patent and achieve similar breakthroughs.

2a) I suspect AEM's future revenue stream will sustain largely based on consumables. I have always wondered what % of their business based on recurring income and what % is based on equipment. My query was answered is evident in AEM corporate presentation dated 28 Feb 2017, and we can observe that 2016 recurring income doubled that of 2014. The very skeptical investor may ask, "Is this true?". One can observe from the youtube video below that testing are performed in a cleanroom. This is because due to contact, there will be wear and tear, during which will generate particles, which will damage the chips. In fact, the same lessons can be observed from UMS business as well, and this question was answered by MrEngineer in the UMS thread.
2b) In addition, Intel could also refresh its existing old test handlers.
2c) Intel is resuming plans for Fab42 (Chandler) in 2020, for 7nm gate size (thanks to Donald Trump?). I would expect Intel to purchase new machines for additional operations.

3) Currently, Intel foundry business is minuscule compared to their core businesses.
4) Next, Intel's HDMT promotional video is just an illustration. As Intel doesn't sell its testers in the market, I suspect Intel intends to keep its technology as a trade secret, instead of patent their technology. From the video, the entire testing process is inside a box and designed to be automated. Does it make sense to have little LCD screens when it is supposed to be automated? How many workers do they need to constantly monitor the numerous LCD screens? Logically, we can tell that it is an illustration.
5) Investing based on the thesis on a potential acquisition is alike to wishing that you have a wealthy long distance relative who will pass away soon and you will inherit his wealth. Just my opinion.
These being said, I am not an industry insider nor familiar with semiconductor technology.
Hope it helps.
