FTTC or WBC FTTC??

The BT ADSL Checker for my number has now changed from FTTC being available, to being delayed. My question is why it now states the term 'WBC', which it didn't do before?
Does it mean I may still have pre WBC FTTC available, if such a thing exsists?

"Your cabinet is planned to have WBC FTTC by 31st March 2011. Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 27.2Mbps and upstream line speed of 6Mbps."

The BT Wholesale use of Openreach FTTC is with WBC, used by IDNet, AAISP etc. Others can use GEA from Openreach.

If you're using a Wholesale checker they've probably just tweaked the wording.
