Questions About MOI's - additional usb dvb-t tuner etc

[are]

Hello, Im looking in to replacing my x86 htpc/pvr with the moi+ but need to ask some questions before proceeding.

Current pvr backend run debian 7 and tvheadend + TBS6985 quad tuner and a 'Hauppauge Nova-TD Stick (52009)' usb.
(The Nova need firmware dvb-usb-dib0700-1.20.fw. need to be loaded before the stick starts, no problems here.)

1) Will this setup work out of the box on the moi+ or mabe the moi pro?
If not can i make it work?

2) Anyone know if there is a second generation of the moi's comming anytime soon? if so any info about them?

3) What version of tvheadend comes installed?

4) can recordings be stored in Mkv and or .Ts format like in the debian builds?

Thanks in advance.
