Buy a 13th gen now? Or wait the core ultra?

I want to buy MSI with 13980hx and 4090.
I need help, should I wait for the 14th gen, as intel changed the design and architecture with claims of huge improvement and AI embedded for the new core ultra. Or it could be just a marketing thing to increase the sales, while it will only improve fake 10% in benchmarks with no noticeable improvement while doing projects?
