For the High Rise Bridge, that is currently the decision for Phase #2, and for the HRBT, I mentioned above they are doing 2 HO/T + 2 GP during peak times. They could've done a 1 HO/T + 3 GP using an outside "shoulder" lane but they chose to make that shoulder lane an additional HO/T.
And you are right, these easily could change. But right now, that's currently the decision made.

HRBT will be a four-tube tunnel with 2 lanes in each tube.  I could see a difficulty in running one HOT and one GP in a tube as there would be no passing allowed.

I-64 Southside Widening and High Rise Bridge financial plan is not really clear about the configuration and the wording seems to imply one HOT lane each way added in each phase.  I don't think that is correct.

Hampton Roads Bridge Tunnel Expansion Project Procurement Update to Commonwealth Transportation Board Feb 19, 2019
http://www.ctb.virginia.gov/resources/2019/feb/pres/1_hrbt.pdf

Excerpts:

Scope of HRBT Expansion Project
-- Settlers Landing in Hampton to I-564 Norfolk (10 Miles)
-- I-64 improvements include 6 lanes of highway + drivable shoulder and construction of 4 lane bridge/tunnel
-- New HRBT tunnels will serve Eastbound traffic
-- Existing HRBT tunnels will serve Westbound traffic
-- Design-Build Contract Value:  $3.3B
-- VDOT will pay for South Island Trestle Bridge Replacement Work (180 days option to identify funding sources)
-- Execute Comprehensive Agreement NLT (no later than):  Apr 15, 2019
-- Contractor LNTP (Limited Notice to Proceed):  Apr 2019
-- Project Complete:  Nov 2025

. . . . . . . .

I talked to the Chief Engineer and asked for some design details.

HRBT will be 8 lanes on 4 separate 2-lane roadways/tubes.
New tunnels will be bored with TBM.
HRBT existing marine bridges will be replaced.
Willoughby Bay bridges will be widened to 8 lanes.
The "driveable shoulder" will be a 12-foot left lane of full-depth pavement.
Two general purpose lanes each way between Mallory Street and I-564.
Two HOT lanes each way between Mallory Street and I-564, seamlessly connecting with 2-lane reversible roadway.
No major rehab of existing tunnels.  No addressing of increase of vertical clearance in westbound tube. (*)
No major upgrade of I-564 interchange. (*)
Mallory Street to I-664 widening will be a future project not yet studied.

(*) At least not in this particular project.

Do they plan on releasing technical drawings / schematics of the project?

Interesting about the westbound tube... so the HO/T lanes without trucks will have a higher clearance than the GP lanes with trucks... I don't see why the HO/T shoulder couldn't be a full time HO/T lane, or hell, if they're playing the shoulder game, why not give the GP lanes a shoulder lane as well? It would involve increasing the cross-section on the outside from a 12 foot shoulder to 14 foot or 16 foot, but worth it IMHO. The only issue is the tunnel - it'd have to be 3-lanes wide, instead of two, but I guess they didn't consider this as an option, and again, fled to more HO/T lanes. It would surely help with traffic congestion by adding another GP lane as well in the long run, but I guess it's too late. This could bite in 20 years.
