Seems with the demise of the Terra, Uwatec have had a rethink on the Luna and are aiming to launch it without a transmitter, heart-rate monitor or mixed-gas capabilities, but with the ability to be upgraded to all three retrospectively (the Terra, if you remember, could only be upgraded on the latter two).
However, looking at the prices it will be in the UK, if you get one with a transmitter straight off the bat, it is only about £150 cheaper than a Sol, and I can't imagine the upgrades for heart-rate monitor and mixed-gas will come in under that amount for both, so it seems an expensive way of doing things.
The problem with the Terra was that it was priced too high for an entry-level (to this range) computer, and by the looks of it, I think the Luna is going to be too much for what it does. Will have to wait and see.
