G-VSXY

Hi,
I flying on VS085 tomorrow and was just having a look to see which of the LGW A333s it will be. I reckon G-VINE as she's currently doing MAN-MCO and should be back in MAN in time to do VS085. But I noticed G-VSKY has not operated since doing the MCO-LGW on the 26th February. Any ideas why? I thought G-VINE was the first 2 cabin aircraft to be converted to the 3 cabin, so it's not that?
