Because they need to make sure gsm or lte is guaranteed to be available in most of the areas that are currently only being served by cdma signals
T-mobile has no LTE. MetroPCS IS "the main LTE network". MetroPCS is 100% of the LTE network.
So there is no LTE overlap, and they aren't shutting down any LTE.
T-Mobile actually has a lot of sites up they've been adding them since the refarming in November last year they're just not available for the public to use yet they'll probably be announcing the 1st couple markets (NYC, San Diego, Las Vegas & Kansas City etc.) when they change plans on 3/27 and also release the LTE GS3 shortly after. Its supposed to be 100mill pops covered by summer then 200mill pops by the end of the year.
They'll be shutting down metro's LTE network as they go along and start overlapping. T-Mobile LTE equipment is much better anyways its release 10 vs metros release 8 equipment. (Release 10 is LTE Advanced)
^^^This isn't even speculation T-Mobile said it in a press release
