^MS mentioned on Twitter this site is going live tomorrow. An email I just received points out that this indeed won't go live without cycle reservations and suggests phoning to book.
So they're suggesting we wind back the clock almost 10 years.
Of course, most of us know GWR, Chiltern, etc still use WebTIS and people can book their VTEC ticket on there (and they get the commission) but if people ask VTEC customer relations or on Twitter then their Twitter team will not tell them of the other online options but will suggest the phone.
On the same email underneath the bit about the cycle reservations there's a reminder that I can still collect sweet, sweet Nectar! I'm registered with Flying Club on my VTEC account, so poor targeting there.
In this blog post there's a screenshot of WebTIS from 2007 in GNER colours:
