I wouldn't wait too long to get into Flash recovery if you believe at all that SSD's will take over.
Flash Recoveries are deceptively difficult to do regularly, and time consuming. There is quite a steep learning curve when you first start doing Flash. Flash is evolving very fast, NANDs are getting more complex than just a huge array of bytes, and controllers are getting more complex with more wear levelling algo's being very difficult, new XOR schemes and encryption.., and if you are going to start that curve after another year or 2 development on this stuff, you have a very hard starting point.
Right now, aside from sandforce debacle, a good number of SSDs are basically just large flash drives. This wont continue for long I suspect with vendors starting to lock down their drives.. making it harder to RE and harder to recover.
Also with HDD, you can say this model of WD drives are known for XYZ, This Seagate has compatible part numbers 001abc... Hard Drives are to some extent a known entity.. But for most flash drives there is going to be a mystery what is inside.. and even over the space of 3 months in the exact same looking, same labelled drive you could have any number of differing NANDs, controllers, PCB and differing recovery steps and values. Try telling the difference between 20 Verbatim Store-n-Go flash drives bought over the last 4 years... all look EXACTLY the same ;-)
As for the tools, we have exactly 1 new tool (VNR) over the last 3 years. I cant see anyone coming out with anything that will rival that anytime soon, and there are only 2 other tools worth anything anyway.
As vendors do not give out really anything that helps DR and DR Tool vendors, all of it is either reverse engineered or guess due to experience of similar know chips and algo's..
Basically what I am saying is waiting could mean you are left behind.
But if you are busy fixing Hard drives, then you might not have the time to spend on flash, so it is going to be a decision on where you want to spend your time.
