Probably you didn't get the goal of Tezos. A self-amending blockchain is something huge, never tried before. It has the potential to take every improvement of any other blockchains and implement it, without centralized hard forks. I don't see overhype here, the project really has a lot of potential. Let's hope to see it live soon.  

Some points from the website:

Decentralized, automated upgrades: Virtually every example of of modern software provides for automated updates, but blockchains remain a notable exception because update procedures are typically centralized. Tezos achieves decentralized upgrades of its blockchain protocol, something no other system offers.

Upgrades without hard forks: Upgrades are decided by stakeholder consensus in accordance to clearly laid out governance rules that are programmatically enforced. This avoids political deadlock and stagnation without entrusting or empowering a single core development team or de factor group with disproportionate sway over the process.

Funding innovation: While blockchain innovation is moving at a breathtaking pace, there is often little incentive to improve existing systems. As a result, application developers have been shoehorning tokens into applications where they do not naturally fit. These “appcoins” dilute the value of the underlying platform more than they contribute to its network effect.
