Hi Zogi,
I am using Storme since more than 1.5 years now, to be very true; Yes there were some issues related to rattling and noise from clutch and dealer was not able to solve the issue but then i involved TATA people and every thing was done. After that i never faced any issue and am loving my machine. TASS is improving significantly. So according to me you can very well buy Storme, for waiting of new storme depends on you wether you are able to wait since there is no news of launch date. Even though it's always better to wait for new model but you will miss the discounts. My advice to you is wait till next model is launched and if it's expensive then i am sure that you can get the current Storme from some dealer.
