VS017 a/c change?

Is anyone in the know aware of the VS017 being switched from an 343 to 346 from 2nd March.

I suspect that it is just in the system like that( as it seems a strange time to switch) but Expedia is showing up as 346 from this date. This flight is always a dilemma for me as I like to catch the last flight out to max the weekend at home but would prefer a 346 for obvious reasons.

Appreciate any information.

Thanks

I've had a quick look and most flights i checked do appear to be on the 600. Maybe they've swapped it at last!
