Is there any plans for MCU that has STM32F407 specs, but has CAN-FD interfaces instead of CAN?

I doubt this design is going to be revisited. Talk to local sales staff/engineers.

Review new parts for commonality of foot-print, 144-pin devices have generally had the best migration path.

STM32G474 has no ethernet but CANFD. Did you look at the new STM32H7 variant?

[Alexander Novikov]

Yes, but, STM32H7 is too overloaded with features I dont need.

[Alexander Novikov]

Generally I need Cortex-M4, >120Mhz, USB FS, CAN-FD (at least 2), and Ethernet MAC. STM32F407 is closest. I see all new MCUs (G0/G4/L5 lines) now utilize CAN-FD instead of old CAN, but have no Ethernet. So I expect some new chip like STM32F407 with CAN-FD. Microchip already has SAME54 - this one is exacly what I am looking for. But SAME54 has lots of drawbacks on overall design of the other chip peripherals (DMA, clocks, timers, ADC etc...)

[TDK]

So the STM32H7 has everything you need but you don't want to use it because it's "overloaded with features"? How is that a problem? Why not use what you want and leave the other features untouched?

[Alexander Novikov]

The problem is its price

[TDK]

On Digikey (qty 1):

STM32F407 is $9.29

STM32H745 is $11.71

I doubt they're going to introduce a new line of chips between those two price points.

[Alexander Novikov]

On our local distributor

STM32F407ZGT6 is about 5$

STM32H745 11$

Given the cost of all the other bits in a project (including the major one of time and effort writing and debugging the code), that sort of price-difference is negligible for small production runs (say 10 units).

And for larger production runs I'm sure you'll be able to get a better price. I've even known cases where the the price difference reverses in sufficient quantity.

Having said that, I've been trying to port some code from stm32f7 to stm32h7 for a long time and I'm still hitting differences.
