MCE2005 Box and 2009 Analog shutoff

I have a MCE2005 Box with 2 tuners (Analog and ATSC) using OTA exclusively.  I built this box up about 2 years ago and most functions work well.  We almost always use ATSC, since all OTA channels have a digital twin in my area.  Could someone comment/answer on whether or not my box will still work when Analog OTA is shutdown in 2009 ??  I recall that MCE2005 required you to have a functioning Analog tuner to operate and setup.

thanks!
