Windows Phone 7 out of date

Will the windows phone 7 be out of date by the time they finally decide to release the phone.  I mean the phone has good intentions and it will be a nice change from all the android phones and iPhone we are used to seeing and using in our lives.  But the phones that are already out right now have the capabilities that the windows phone 7 will have.  I guess we will just have to wait and see when the phone comes out.  Who will be buying the new phone?
