Microsoft have gone gold with the Hotmail Live service and from Monday the 7th of May it will be available for all customers to migrate to:

If you migrate this will result in Gotmail no longer functioning. Additionally, during this cut-over it is quite possible that Gotmail may start to malfunction or fail to function entirely.
It does appear that you can retain the 'classic' Hotmail for the moment:

But there is no clear indication whether this is Microsoft's long term plan.
All is not lost though, Jos De Laender, has developed a Gotmail variation, entitled GetLive, that can retreive mail from a Hotmail Live service, albeit with a reduced feature set.
