The real work will be in getting developers to update apps with native code for the new 64-bit platform; but it is obvious that the 64-bit hardware is coming soon, much sooner than it will take Google to update Android for 64-bit. (http://www.88phones.com)Original Mobile Phone from China This will lead the whole ecosystem to end up in the same vicious cycle where manufacturers will push hardware before the software is ready, and then will likely be slow to update software once the optimizations are done. The first part of the problem will likely occur not through any fault of Google's, but rather because manufacturers (read: Samsung) will want to make sure they have that 64-bit processor in the newest flagship device - and more importantly, in its marketing campaign - before Android is ready to handle it. Then, once Android does get the update to 64-bit, users will have to wait a bit for manufacturers to push out that update.

Of course, this isnt necessarily a problem for consumers per se, more of an annoyance for those of us who pay attention and understand the real story. All it means is that we will all be subjected to marketing campaigns touting features that offer no real value, which is nothing new. We've seen plenty of features gracing various marketing campaigns that don't really make much difference to the majority of users, like Air Gestures, Face Unlock, and Siri. Samsung and others will undoubtedly market that their products have 64-bit processors, and will conveniently leave out that they offer little to no benefit because the software isnt ready. But, that is the way marketing works all around anyway, and the average consumer wont know the difference anyway.
A slow path to faster speeds

While hardware manufacturers plan to jump the gun and put out 64-bit hardware running software that isnt optimized, Google hasnt mentioned at all when we should expect a 64-bit optimized version of Android. Getting there will doesnt look to be that rough of a road, but it will certainly take time to get there. So, its impossible to say when Android will be fully optimized from top to bottom.

The earliest we could hope to see Android with proper 64-bit support and optimization throughout the system would be in the summer along with the Nexus 7 (2014), but even that is pushing it too much. More likely, well see a minor update to Android 4.4 KitKat at Google I/O, and Android 5.0 (Laffy Taffy, maybe?) with proper 64-bit optimization in the fall with the Nexus 5 (2014). Even then, users will have to wait for manufacturers to update devices; and, to make things worse, that hardware is likely going to be claiming 64-bit on spec sheets well before Android is ready.

All of this needs to be sorted out, because ARM processors are quickly hitting a performance plateau, because of an outdated instruction set architecture (ISA). ARMv8 has introduced a completely new ISA, and made the switch to 64-bit, both changes which will lead to faster speeds as long as software is optimized properly. Unlike on desktops, the argument about hitting the 4GB RAM limit is nowhere near the most important factor when talking about the performance benefits of moving to ARMv8 and 64-bit. Clock speeds cant get much faster without causing heat and battery issues, and adding more cores will only get you so far, unless they are specialized cores to offload low-power processes, like weve seen with the motion and voice coprocessors in the Moto X and iPhone 5s.
