Here what I feel is going to happen. Tablet devices are only going to get faster and more efficient as technology progresses. When this happens software from a standard Microsoft operating system will also run faster and with less battery power. Microsoft also released it
s tablet called the Windows Surface which also supports Adobe Flash. Flash will eventually work on these devices with little or no effort. Right now that is not the case, but be sure technology and hardware always improves, it has to! It is just the way industry works. When that does, one way or another, somewhere or someone will have ways of continuing to run Adobe flash content and all the existing games, applications and animations that are already out there on the internet!
Here is a good benchmark article on Flash vs. HTML5!
Also in that time don't you think there will be just that much more flash based content on the web? Don't you think that maybe Adobe will come out with another way to deliver Flash based content to mobile devices? If they do not, they will lose a lot of money. It comes down to the all mighty dollar and to simply abandon it would not be a good business decision, at least not one I would make. However, if they do another company like CloudMosa will develop an application like a new available web browser will be available and support flash on the I-Pad, I-Phone and other Apple devices. Also, Windows 8 on mobile devices will function just like it does on a desktop so if you buy a mobile device with Microsoft Windows 8 on it, you will still be able to play flash on it.
Are they just going to forget about the developers when they can offer Flash Professional upgrades and new releases to them and make more money? If I was running the company, I wouldn't just abandon the existing market place? That is like throwing money down the drain and certainly doesn't seem like a wise decision.
One of the biggest complaints by Apple was that flash is proprietary and that is unfair to the web. Well, ok, you can make that argument but in order to make a game for the iPad or iPhone, you also need to have proprietary software and a Mac. So they are just being hypocritical in my opinion. Mac's aren't cheap. Now I am not against phone and tablet applications by no means but quite frankly, a lot of good iPhone and iPad games also run slowly because the lack of CPU power currently!
Currently the demand for Adobe's creative suite is extremely high. If they were going out of business then they would not be releasing new version of their software. They may adjust their software to work with different platforms like HTML5 so that in the event that when someday HTML5 will perform what Flash can do today then developers have multiple options. To me, it sounds like Adobe is preparing for the future not abandoning it!
