In the UK, you cannot sue anyone for 'future promise'. So basically a company can say that their product will do something in the future and if you buy it on this basis and the company fails to deliver, you cannot do anything about it.
... a statement made as to the future could not be false or misleading, because such a statement did not become untrue until the property was actually built and therefore, at the time when the statement was made, it could not be said to be true or false.
...
However, the effect of this decision is to require prosecutors to prove that the maker of the statement did not intend to do what was promised at the time the statement was made. It is notoriously difficult to prove intention, and this may well prove to be a difficult prosecution to bring.
Which basically means that you would have to prove that the intention was to not deliver. Obviously if you were UK based, which you are not, I would say the chance of this was about as close to NIL as makes no odds. But I am sure that a solicitor would be happy to take your money, in which case, you may get them on future promise as it would be clear from the start that the case had no chance of winning but the solicitor would be happy to take your money irrespective!
I had this happen to a Silicon Graphics workstation that I bought. SGI promised that it would so something but in the end they never delivered on that piece of functionality. I could do nothing about it. 'Thankfully' I did get my own back because what they did deliver had an inherent design fault and when I came to upgrade its capabilities it did not work. It took SGI ages to fix and I got much of the upgrade cost for free.
